Dodge D50 muscle truck
Posted 18 April 2011 - 01:34 PM
While waiting for some warm weather to paint a bunch of half finished models, I dug the D50 out of the cupboard with an idea to experiment and turn it into a......... what? The previous owner/builder had securely glued on the optional fender flares so that kinda left me without a whole bunch of choices. Circle track race truck wasn't in the cards, perhaps a dragster... naw! The logical option was some kind of custom street truck but I wanted someting different from so many of those other mini trucks.
How about a Muscle mini truck! Stock body and chassis for street use but with a Hemi! But would a full blown hemi fit in that small engine compartment? Only one way to find out....!
My first attempt failed miserably. Using the stock chassis and front suspension... there was no way! But meanwhile I had cleaned and stripped the body of paint and added a quick change rear end into the truck. At this point I should tell you that I'm no mechanic in real life so I'm sure there will be flaws in my build in the real world. If you see any as I proceed, please let me know and I will try to correct them along the way (if I can).
First pic is the glue bomb disassembled:
Next pic is after stripping the body of paint and cleaning up the chassis a little:
After the lowering, reassembling and repairing of the front suspension, adding a roll cage (don't ask me why!) and adding the quick change rear end. At this point I tried a mocked up Hemi between the rails and realized that some major changes needed to be made.... more of that in the next post.
Stay tuned.... I've actually dome more work after this but the pics are still in my camera's memory...... By the way, if anyone has a spare left (driver) side taillight lens (mine's missing), please let me know.

Not sure how well I will be able to finish the paint on this build as the body is pretty badly damaged from excess glue, rough assembly and handling, but I'm not looking for a show truck with fancy rims and such. Probably try to finish it as a late '70/early 80's backyard custom driver built by someone with a bunch of ideas but not a lot of money, mechanical and bodywork skills to get it really looking smooooth....... wait a minute, that sounds a lot like me! The theme will be a transplanted Hemi from a "period used car lot" find. Back then, Hemi's were not worth what they are today, and usually a complete car in running condition could be found for a couple of hundred bucks. Oh, for the good old days!
Pretty much a "parts box" build, using whatever parts I can find in my stash.

Trying to keep this build all Mopar (was the D50 a Mitsubishi?), I checked my stash of unbuilt models and came up with this '68 Roadrunner kit from my pile of started but never finished collection. This kit surrendered its 440 (I think it's a 440 but could be a 383?) but I'm no Mopar expert.
Checking the Roadrunner front subframe it appeared that it would be able to replace the D50 front rails completely and solve my engine mounting problem. It also had inner fenders, a firewall and rad cradle that looked like they could be transplanted into the D50 front end with some fairly minor modifications.
I had to remove the D50 inner fenders, rad cradle and firewall and cut down the size of the Roadrunner ones, but it seems work out pretty well. I'm hoping the body, chassis, wheels and wheelwell openings will all line up after surgery, but although I measured and checked twenty or so times before I started.... you never know!
Out came the trusty razor saw and, with trembling hands, I started to butcher the roadrunner chassis and floor assembly. Once started... no turning back! (By the way, for you Mopar guys, dry those tears... I have two more of these Roadrunner kits to build as well as at least three 1/24 diecasts.)
Gluing the frame back together was done with superglue (probably should have used epoxy but I'd run out and it was late at night) and a couple of reinforcing brackets but I'm not sure it will hold up to the amount of checking and double checking I usually do during a build.
Here's how it's coming together:
Front rails removed and replaced with Roadrunner subframe:
D50 engine compartment gutted for Roadrunner assembly:
How the new arrangement looks with the engine in place:
And finally, an exploded view of how (I hope) the whole thing will come together:
Keeping my fingers... and other parts of my body...... crossed!

Thanks Brad. Boy, you're a mine of information and it's always there when I need it!
Somehow, I'm not sure this will be the best handling truck in the world! All that front end weight would probably send it into the ditch at the first bend in the road! However, I'm sure we can figure out a way to modify the suspension a little, but that will come later. Any ideas?

When we were racing, we tried for a 50/50 front/rear weight bias. However, with a FOX Mustang, that is almost an impossible task. What we found that worked was diagonal balancing, where the RF/LR weight was the same as the LF/RR weight. This way, the car has the same weight shift/handling loads on the front corners in either direction, and the cars rear was also load balanced. Now, with that said, we would spring-load the right rear with a slightly higher spring rate to help compensate for the torque-squat we would encounter blasting into the straight from exiting a corner. But I digress, this is all rear car stuff and will in no way affect the model!
Keep at it Tony, I am watching.

Lowering the engine and setting it back is out of the question due to the confines of the engine bay and suspension. New style tubular K member doesn't really fit with the build period, which is set in the early eighties and basically a "backyard" build. (Does that sound familiar - maybe Billy has another buddy?) But maybe I can triangulate the rear frame for a little more rigidity, and also attach/weld the cab section to the box for the same reason.
Neither kit includes any steering assembly at all but I may be able to cobble something up from my parts box to get a more detailed engine bay.
From all your good ideas, I think I will be limited to some heavy duty springs and shocks, maybe a rear sway bar and of course some wide (for the early '80's - Polyglass G70's?) tires, and front rotors. This is going to be strictly a street cruiser and weekend drag strip contender!
I'm not in a club and don't enter competitions with my builds; so I usually keep them pretty simple as long as they look good to me on my shelves and in photos and make a certain amount of sense!
(Side note: Now I'm looking a little differently at the '86 GT Fox in my garage.......!)

(If you ever have any questions regarding your 86, just ask.......I might be able to answer them!)

that hemi will be right at home in that pupy and i think the fenderflares will look good painted black (to look like the ABS aftermarket ones)
if you want to you can send the remainders of the roadrunner to me and ill get her good as new again

most of the early fender flares were fiberglass and were painted the same color as the body. The later Poly flares didn't come along until the early-mid 90s, and they were either Black or 'Trim Black...gray'.

diymirage: The black fender flares idea (Bushwacker style) had occurred to me as well, but I'm not sure they were available in the early eighties. Do you know? Checking out some old Truck magazines from that era, most of the fender flares seem to have been painted the same color as the body. (PS: Sorry, I have plans for the rest of the Roadrunner!)
lol, I wasnt even available during the first part of the eighties
on top of that dodges were rare where i grew up (even today it looks like 80% of the cars on the road here are european and 80% of those are german)
looking forward to seeing how the roadrunner comes out
on a side note,you should scratch up those flares to make em look like they went through the woods

I like how ya got the Roadrunner chassis into it.
Those AMT Roadrunner kits make a great donor for anything Mopar
For some extra Road Grip, what about throwing some extra weight into the bed.
Maybe a loaded tool box?
On a Funny side note, My dad is an All American Mopar Guy and has owned 3 D-50s.
Weird, I should stick a Mopar Emblem on my cars so he likes them

have found my 2 D50 models when I moved in 2008 had one kind of along
this idea only was using Dodge nascar motor and think I had cut front to tilt
open had some tires planned to make it a street machine like i saw done to S10's
in the magazines. the other was still in the box and was no where to be found so
it got left hear they never did find it.
because i had asked if they found them to save them for me oh well now i want
to get one and then get my parts out of storage and try some ideas with my own
build like this.
