1965 Dodge A100 Monster Truck "Doomz Day" build NEW Progress 10-20-2016

Well its been a bit, a bit of trial & error (I have to admit to it, I had some issues with getting this right!) BUT thats why I keep "trying"..... WELL, to give everyone a heads up, keep in-mind, I want this thing to be the BIGGEST, BADDEST, engine ANY of you can EVER imagine! To the point of, when you see it, it jumps out and bites you............. Thats the goal here (I mean, really its name after all is "Doomz Day", right!?) -NOT because of the meaning of the term "Dooms Day" but after the name of the engine that powers it.. the "Dooms Day Machine" Chrysler called it! BUT I'm playing off that, with the name and a little twist with the spelling, but you all get it by now. And, those who know me knows how I roll that way!
So anyway, to start, I originally wanted to use the 14-71 Superchargers that I molded and have made already.... Sadly, I wasn't pleased with their looks. They'd be OK on other builds, but not this one..... I just wasn't "feeling" them in the sense they'd be used here.....
SO, with that, I sat out to build something...................different? Yeah, they sure are "different". Kit-bashed, yes, from existing parts, made to be bigger then originally made by the factory. Started with parts from the S'Cool Bus kit, that I saved....

Those Superchargers are monster-ous, BUT they are after-all 1/24th scale, NOT 1/25th so I made them fit the suit, and slightly under-sized them, BUT still kept them "BIG" for looks.... IF that makes any sense!

Now as you see here, I have the newest parts set out, with the first BIGGER idea I had, with the 14-71 resin part setting with whats to come! To start, I took the factory S'Cool Bus blower "body" and split it down the center.... This was going to slightly "shrink" it. Narrowing it, makes it fit the Plenum a bit better, and gave it a slightly longer looks thats not so wide. I re-built it adding in 1/8th inch thick rod, to the center, so I didn't make it too narrow but took out about 1/16th of an inch in width by doing this! SOLID bar too, makes it easy to "shape" it to the form, of the blower body itself! And giving a good base to glue too!
Then, you see the front and rear blower body plates, those have things done to them as well! Between the yellow blower body, and the resin 14-71 I molded you see a clear piece, that I machined! This is a body extension that a larger then 10-71 would have! This will be added to the back of the blower body!


That clear part, mounted to the back of the blower body..... This clear part? BOY, I tell you, that thing was difficult to make and get it right! See, there is no "true way of knowing what looks right, what is too big, or too small! Because its "looks" NOT dimensions! Plus, in making that part, you first have to turn the part down to be round rod..... THEN when you think you have it, right, you then have to put it into the milling machine, to mill to flat spots on it, top and bottom! BUT, if the round turning isn't right, when you mill either of the flat spots, you can't go back and turn the round part down any further as the lathe won't grab the part right to make the turnings true! SO, one small mistake? You get to start all over again! Thank God, these parts are just little, It took 2 tries before I got the 3rd one (seen here) right!

This shows the front of the blower body!
Now sadly, I didn't get pictures of the work done to the front and rear plates for the blower, BUT as your about to see, I did some work to both those parts as well!

The front plate that has the blower drive pulley extrusion, got a thicker plate as the real 16-71 would have.... As well the rear plate, also got a thicker plate base too, these "extensions would be for bolting reasons, and flanges for such as well as size all in one!
Now to take the resin 14-71 that I mold, and sit it right beside the NEWEST creation my 16-71 Supercharger....

A tad difference in size, yes? I LIKE it! The new one looks GREAT! After a couple of tries, I find, one day, to let it sit and think about it, makes all the difference!
Now so that all are aware of it, I had to make these TWICE! As I'm using Double inverted-"V" Superchargers on this build!
Stay tuned, more to follow! Comments are always welcome, ENJOY!

So As I mentioned, I had to make 2 of these Superchargers, which I did.... Got it all "right" on the 3rd try! And then got to seeing how they fit that Tunnel-Ram Intake Plenum. WELL the "Foot" print of the supercharger was just enough, that I HAD To set out and re-make then Plenum too! GO FIGURE! BUT, the hard part was done on it! All I had to do was lengthen the height of it, and cut the point in the middle "in" a little, to get the new superchargers to fit the old sized Plenum, ALTHO, it made me have to create a NEW Plenum! Thats alright. The old original, I plan to mold and off with the intake "base" Tunnel-Ram ports! (To offer something other then) for that intake!

Two 16-71 Superchargers, and a new Tunnel-Ram Intake Plenum, siting & waiting....
Once assembled, the Intake set up alone is BIGGER then the engine is!!!! I'm OK with that! As you'll see in a minute!

SO once all had sat a bit, a few hours, I took and got primer on the Plenum, to be painted with Alclad "Dark Aluminum" to match the Tunnel-Ram Intake base.... -I then took and painted the Superchargers with glass black, to begin the start of chroming them also with Alclad Chrome paint through the air brush!
I let it all set as the painting step took a couple days to do.... BUT once it was all ready to go and be handled for assembly, I just could not hold back! together it went..... Then I realized, I got absolutely NO pics of it going together..... Ohh well, heres what it looks like TOGETHER!






W-O-W......
I'm AMAZED at just the sheer size of this thing! The engine is BIG, YES, but with that induction set-up Holy Mother of God! And to add to this? I'm no where NEAR done either! I got the plenum with the superchargers on the engine, to stay, as well as the valve covers, as well as the first phase of belts! In the back-ground of the pic, you can see the awaiting Distributor/Magneto's, with wires! The superchargers are mounted in such a way on the plenum that ALL the custom turned Billet Aluminum pulleys will line right up for the belt! And thats gonna be a FUN ONE! I'll enjoy it tho! This whole INSANE build, I'm enjoying so.... Stay tuned, more to follow!

Now to get ya all worked up....... BOTH the "Old" 426 DOHC Hemi, beside the "NEW" and improved, 528 DOHC Hemi!




Nice! The 2 of them side-by-side are almost "equals" in side! I did NOT set out for this purposely but is an added bonus I have to say! The new one will be made to fit into the trucks frame just as the first one was, and that way, all will fit right from there on out for the build! I am keeping the exhaust pipe work the same as I had planned. Also the Twin-Turbo's will be made exactly the same, as the radiator and intercooler are not in-place yet so, there is a little wiggle room fitting all this and making it right!
The one thing I AM going to do, it fit a plate to the center line of the Superchargers to have a "level" setting set of carburetors on EACH Supercharger! SO, they will be "level" not mounted on their side type thing... keeping that "Long-Ram, Tunnel-Ram" looking effect! LOL
BUT, now in order to keep going, I have some details I HAVE to add here, as if I go any further on the build without detailing, I'm gonna pay for the mistake! LOL
I wanna put a water pump on this bad-boy, but I'm not sure how to go about it, (electric powered YES) but where to mount it! Most Mopar engine mount the water pump to both top side edges of the timing chain cover, and then on Mopar engine in drag racing they show it going to the top of the head through the valve cover, on the 426, BUT then the 392, has it cooled through the top front, inside corners of each head......... NOT sure how it connect to this bad boy, I'm leaning towards it connecting to the stock location of either side of the top of the timing chain cover! -GAWD, thats gonna be a FUN task!
Thats it for now! Stay tuned! more to come as things happen, As always comments welcome! ENJOY!

Man... you sure are a crazy detail freak, but with a sci-fi-ish mindset... Compared to this, anything I have ever done or will ever do about modelling is merely a toy store deal. Reminds me of those builds when guys build anty-gravity star-wars-like things out of car model kits. (Have to admit most of the engineering aspects of this build are over my head.)

felhasznaaloo,
Thanks! Yeah it has that effect, BUT its not a Sci-Fri type deal, just a big in-you-face Monster truck that well. I got the idea from the pick-ups that have those little tracks, that are quad-track set ups to fit normal stock size (and height) trucks. BUT to be a lot like the Gravedigger effect and age.... And to be "different" a Dodge A100!

Now for me detailing ways, I always said: "How do you build a better model?" You know the REAL thing.... Now, granted not all of this would be real, its Fictional, BUT to that as built it looks and will look as if it would work! SO with my knowledge of the real high performance stuff everything Mopar, I put all that into one engine! Just to make it stupid powerful looking!

AND to think this single one truck model as spun out of control to build a full-on race team with the same name and colors as well as a hauler possibly 2, as I'm doing a race car too! A Dodge L-700 is going to be the tractor to haul around a Pit-Trailer to house a Pit-Garage within it, as well as haul this truck!

This build is simply awesome John. Love the detail and the scratch building you have going on this build and looking forward for more. Cheers Steve

Thanks Steve!!!!! There will be some updates to this one in a day or so......... I gotta take a few more pics to go through with it and then you'll all get to see what I been up too!

More superbly detailed scratch building there mate.

Some awesome work here, well done. Not sure if I missed it but wouldn't you need a sprocket  to drive the track gear?

Thanks guys! All of this is a buncha fun!

A LOT of scratch building, yeah you bet!

As for the drive sprocket, Its gonna be done with "pins" not an actual gear/sprocket type set up.... I got 3 sprockets and not 4 of them so I'm gonna make them all fit the part.... one hole drilled and pin into it, as I go! I'm a ways off from all that hyped up detail on the tracks!

Well, a little more done to this build! I am slow going on the details as A LOT of it HAS TO BE well thought out as it really is A LOT going on, in such a small area, so things have to be placed as just so, to not hinder other details that are major pieces to the engine.... SO all takes time and a lot of thought going in, SO with that, I went one to get the plug wires in-place on the engine! In my last update with pics, you seen the Blowers on the inverted "V" Plenum, that whole sub-assembly was merely "setting there" for the pics, all mocked up for looks sake! So, having that HUGE Intake Plenum, with the Blowers, I had to apply the Distributors, and all the wiring for the plug wires, remember DUAL-PLUGS, meaning DUAL plug wires too! 2 Distributors, & 16 plug wires total had to be fished through the Plenum's Tunnel-Ram intake base! So, with that, I color coded, the wires, one Distributor has Red wires, and the other one has Black wires! BOTH Distributors were turned in my Unimat, and then polished, BEFORE the 2 of them were mounted to the drive plate under each of them! The holes for the plug wires was drilled AFTER the polishing stage to keep the "polishing Compound" from getting in the holes, and hindering the glue adhesion....
Then going forward, the front Distributor, has the red wires, and the rear Distributor has the Black wires! Meaning, the FRONT plug locations of EACH cylinder will be getting RED wires, the REAR plug location to each cylinder will be getting Black wires!
So with that all said, I began by running the closest wires, first.... The Black ones....


All nicely ran to their proper locations, and looks pretty "natural" laying.... I was pleased with this and kept going!
I went on to get the Red wires in-place to the proper locations on the engine....



LOTS of wires for merely one "type" of detail! I let 2 wires "loose" for the Coil, for each Distributor! I'll be running dual MSD ignition boxes to those Coils as well!
A little update, BUT a lot of miniature work! (I'm now focusing on the intake Plenum, and all the details that will be in and or around it.... Stay tuned, more will come as things are done (and pics are taken), as always Comments welcome, ENJOY!

John looking real nice and neat but I would hate to change those plug wires in the real world. Cheers Steve

Steve,
Thanks man! Yeah they sure would NOT be easy to change would they? -One thing to help would be knowing that they're color coded per cylinder, making it easy, but your right, it still be a bit of frustration to accomplish.... BUT on an engine like this? Where else ya run 'em "safely" away from all the belts!!!! LOL

Well now the details on the intake on this engine has been a mystery! All in itself, as I really was unsure of the direction, in to which I was taking it, or it was headed. Had no real direction actually, building it as I go.... With a little inspiration, and some aspects that I seen else where that I liked and then tied them all together into one... Thats pretty much what this is!
With that, looking at the Intake Plenum, with both Superchargers, and how its all going together, I needed to break up all that silver and shiny on this part, SO, I took and painted the "Ribs" of the Superchargers Hemi Orange, as well as the back of the Superchargers. THEN, on the side I added a "Label" to the engine, to match the color already in use!

I think that breaks it up nicely! Granted, this engine is NOT the same colors as the truck its going in, I made it "factory" colors" to that of the actual engine. As really in a build like this (even in real life) things would have to have been made custom for such a design (Even tho fictional) This engine needed realistic things done to it, in such a way to make it believable to be.
That word "HEMI" I plan to write in black "DOHC" in the Orange "H" where normally it would have "426" and then I will denote engine size else where on something else, possibly the side of the Turbo Plenums, or the sides of the BIG Supercharger style blower hate.

Did not do a lot of tu-tone painting on the front of the Plenum, there is going to be A LOT going on here anyway, so I really don't think it needs any breaking up of the colors.... As you'll see in future updates!

Rear plates of the Superchargers look pretty good! I like how they turned out with the Orange. The whole sub-assembly, looks good with just a little Orange added to it. As time goes on and things happen, there will be other colors added so, just a little here and a little there is all thats needed as you'll see, A LOT of detail is coming tho! I have drilled all the holes for adding the NOS piping to the Supercharger mounting lip! Thats to come! Stay tuned, more to follow, As always Comments welcome, ENJOY!

So as mentioned I was getting ready to do more detail to the Superchargers, whether that be the NOS piping or the start of the carburetors. I had to get to the point to have to sit and think what needed done FIRST so that I would not hinder the next detail and make detailing "difficult" SO, I went on to think how I was going to use/add the Carburetors.... This task was just that too a TASK.... I had to think what it take to make them happen, (I had already had those I wanted to use choose out, and painted, simply waiting in-line to be used!) BUT to that, how did I want them? You know? I mean looking at this whole set-up, it has a specific "feel" to it, doesn't it? I mean really, it looks and has that feel of a Mopar Cross-Ram, sort-of! SO, looking a bit further into it, a Mopar Sonoramic Commando type thing, without the Long-Arms and without all the compound "S" curves of the Ram runners that, the Sonoramic Commando has.... BUT it did have that feel to it. Or so it seems to me!

SO with that, as you all are aware of, I'm gonna be running four, 4 barrels carburetors, 2 per supercharger! SO, what I plan to do, is I took the Carburetors and did all the detailing drilling each needed. And then picked out what carburetor was going to have the "inside" effect, meaning throttle linkage, and such, was going to be places somewhat between the 2 carburetors! That signifies "inside" As the other or opposite Carburetor that would outward facing making it an "outside" carburetor.
With the above picture, I have 2 opposite corner Carburetors mounted, those 2 carburetors are the "inside" ones! WHY opposite corners? WELL, thats a good question! I ran them this way to have ALL the linkages running between the 2 sides! SO will not only run correctly, BUT the linkages will run like that of well...... a Sonoramic Commando Intake!! And or, a High-RPM "Cross-Ram" like the Ramcharger 426 Hemi had..... With just lengthened drive rods!

I think with all the details going into this, this will look GREAT!

As it seems this intake set-up just keeps growing..... Well yeah, sort of! The general "size" of it is done, but adding all the details to it makes it grow in size. I have yet to get all the carburetors in-place, as I got to get to the plumbing of them as well, BUT first, I had to get them situated in-place, on 2 of them to act as a counter so that the other 2 go in-place correctly, BUT before I can carry out the detailing work of the carburetors, I have to get ALL the top-side NOS piping in-place, so doing a bit of thinking things through, and doing some set-up to get the stage ready for the next detail, well.... That all showed me that what detail has to go on first so not to hinder the details to follow, it all has a specific "shopping order".

A pic from above a little over-view of the carburetor set-up....

SO then, with the opposite corner Carburetors in-place to stay to have them set the stage for the other 2, I seen in adding these, that when I go to detail, them, I would have to have the NOS pipe work already in-place BEFORE the carburetors can be detailed at all..... SO this got me thinking.... What was I gonna need to make this happen! The NOS system would need 2 manifolds for the NOS per supercharger! The lower inlet ports on the blowers lip. And then it need the upper ones just below the carburetors (a lot of times thats done with a plate the carburetors sit on!) SO, I thought, I'd get the lower NOS lines in-place that be the "inside" of them in the inverted "V" Intake Plenum. This pipe work will be added to the lower edge of the Superchargers, but run to the rear of the superchargers to keep a semi-symmetrical look going on.
In order to do this tho, I had to think of what I was going to use as a Manifold for the NOS.... Remember, there is 2 Superchargers, meaning twice the work, and to that, well.... EVERYTHING has to have a Left & Right version.... SO, having said this, the manifolds for the NOS? Theres no real detail made for those, nor if there was would I of all people have 2 of them, never mind having 4 of them! (This one engine would need 4 of them!) SO, having said that as I normally do, off to the scrap pile I go.... To see what I had that make a Manifold from, and then got to thinking a bit more into it, where, and how was I going to "mount" it? So I pulled materials to make the manifold from and then while looking for that strip stock, I got to looking for "L" angle thats a tad bigger then the material the manifolds would be made from.... I sat down and figured out in what way, the mount "L" angle was going to best suit the manifold, and then got to drilling the manifold, One manifold per edge, meaning 4 pipes to the Supercharger one to "feed" the manifold, & LOTS of fittings!


So I got it all figured out on how it was going to be, and made 2 manifolds with mount, painted them, and as soon as I could got the manifolds in-place to sit and dry so that the pipe work could begin!


Manifolds mounted inward of the 2 superchargers, And one NOS pipe with fittings in-place one adjacent from the other.

Once I got a rhythm going, I left 'er rip! Those pipes? Are NOT easy to make! WOW I mean, you want to have the looks I got here and believe me, It seemed to take forever..... BUT the end result? I'm VERY pleased with!

They're not 100% symmetrical from one side or the other, but from the looks they're close! I'm happy with them as they are!


This looks GREAT! I say that it was difficult to do, and it was, but I had fun making them all look as seen here! I'll also mention here, I used a different type wire for these! As the rest will also get as well, this is wire used for windings on a electric motor, on the Armature. The look of this made for a GREAT looking NOS piping set-up!

A shot without the bright flash of my camera.... The piping is DARK Orange/red in color almost an Anodized look to it, (Reason I picked it) and the size happened to be right for this! And one plus to it, was it was pretty easily to bend, so not a lot of pressure was needed to form each bend. The hard part, is making the bends in the right places!
Thanks for following along! Enjoy!

So in between times painting and gluing. I had a little down time to spare on and off on this build, and needed to keep busy and try to make a little progress, SO I sat out to see what other "details" needed added, painted, etc. So one part this engine is missing? The starter! I wanted this part to represent the high end and high torque starter that it would need to be.. NOT needing to be is the small one to not be "wrapped" with exhaust work, at least not this build!
So then I took it and went on to make it a High-Performance Starter....


Not to shabby I think it looks pretty good! (I have to say tho, the added red "Solenoid" makes it look the part, thats for sure!) -And really that added Red to a starter is just a bit different for me..... But, I like it!
This is all for now! I'll have more as things happen and pics are taken! As always with my builds, comments welcome & enjoyed! Thanks for following along, ENJOY!

That twin blower set-up is just mind blowing mate, AWESOME work John.. !!

Thanks Dale! Much appreciated! I tell ya, tho, that Blower set-up even for me is a bit mind blowing, its almost surreal! I mean its got that Jump out and bite ya feel to it and thats what I've been seeking all along.... Even the first engine! THEN you got my twisted designs in my head and thats just what this is.

If you remember in e-mail, I mentioned that I wanted a twin 14-71 Blower set up, and it spun out of control (In a good way) to become twin 16-71's!!!! -Just because I didn't like the looks of the 14-71's in Chrome! PLUS as you know better then anyone here, I wanted this engine to be the biggest, baddest, meanest, thing ever devised! SO.. I think I'm achieving all that!

I don't have enough words for this build John, unbelievable
Anything with a Hemi catches my attention but putting it on tracks is the real clincher for me (love tracked stuff). And those OTT power plants are a treat, love the twin turbo one!!

I'm looking forward to seeing this on it's .... err tracks!

Thanks tj..... Question you lost me on something you said... the meaning of "OTT"????

I too have a "thing" for "HEMI" -ANYTHING! So.... but ya couldn't tell by no means, huh? LOL Then you have that fact that "tracks" get WAY BETTER "TRACKion" then tires..... and with a monster truck, WELLLLLLL. You see where thats going I'm sure.....

So that your aware, this "new" power plant, is gonna have Twin-Turbo's just like the last one!!!!

Over The Top ... without sounding negative

John this motor is simply insane, in a good way and love all the detail you are putting into this build. Gets better and better each update. Cheers Steve

Thanks for clearing that up! I was unsure of the meaning as thats the first time I've read the acronym so... I had to ask so I knew what I was reading! LOL And yeah, you'd be right, it is Over The Top! -Specailly the engine! (Not that the truck itself follows to far behind!) LOL
