Anybody done that with mopar unibody? Of course bringing the engine/trans with it is the solution. Anybody seen or done this? How tough of a project is this? I'm guessing anything less then 6" is not worth it.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I'd say the further back you can bring the engine towards the center of the car the better. The engine and trans is a very heavy subsection of the car. Let's assume it's 800 lbs of a 3600 lb E body, that's 1/4 it's weight. Even if you could move it back 3-6" I'd think there'd be quite an improvement. As far as cutting the firewall and moving it back 6" I think you'd have trouble putting together some new mounts.

IIRC, feets had a '68 RR K-frame in his Hot Rod which moved the engine back and/or lower an inch or so.

I had pondered putting a FWD drivetrain in the back of my 65 Cuda, looked at the LH car setup and even did some initial drawings, but the 3.5L V6 had little support and I ended up deciding the lack of HP was more detrimental than the increased handling capability.

So I suppose a turbo was not in the cards for the Hp issue? Likely nothing else in the drivetrain would be up to par anyway. Were you planning on reversing the engine for a mid engine ( dealing with all that entails, or go porsche and just hang the engine off the back. Interesting never the less.

What about moving the engine as far back as you can, and lowering the powertrain/drivetrain. It'd obviously tackling the sprung weight in a different way, but seems more attainable and net positive results.

If you can't get it closer to the center of gravity longitudinally, lowering the center of gravity is the next best thing you can if you have to keep the same components. dry sump, custom headers, r&p steering...perhaps entertain relocating the radiator to the rear of the car with some good fans and fancy ducting/plumbing. [off-road applications do this all of the time successfully]

Dishing the firewall is common. hot rod guys do it all the time. I think the bigger issue is the t bar cross member as the hole the tail shaft passes through and trans floor hump will ultimately limit how far back you can go w/o making it a total science fair.

Every FWD vehicle that Chrysler has made, to the best of my knowledge, has most of the engine and transaxle forward of the axle centerline.

The LH series even more so. Since it's engine is not transversely mounted, but longitudinally. If you've ever seen how the Olds Toronado or Cadillac Eldorado were set up back in the day it's similar.

I would have to turn the LH drivetrain 180 degree out to get the engine to behind the rear axle.

As for a turbo, thought about it but this was back before the Megasquirt was around and hacks were all that were reasonably available to fuel it. In any case it may not have been a smart idea http://www.allpar.com/history/interviews/marc-rozman/6-exploding-turbo-33.html

There is a guy on PT.com building a 64 Plymouth with about 6" of setback. I thought about moving mine back enough to use a front sump Gen III pan but didn't want to jump off that cliff with this car.


Mopar to the bone!!!

I don't think I'd do that to a Barracuda, but might be fun with an old 4 door Dart or Valiant.

Why not?

It's not like a 65 Cuda has some value. You try selling one and you'll see.

Because I'm less liable to use a collectable car for something I'm going to beat on. There's a fellow in a town near where I live, has a 66 Barracuda, 273 2 barrel, wanting 8 grand for it. Problem is it's got bondo in places and the repaint in factory color looks like it was put on with a roller. Find a nice cherry Barracuda and you'll find they won't be giving it away, no matter what the year.

As you found out, no one is giving away clapped out bondocuda's either.

I have a 65 Cuda. It is worthless, even pristine.

Asking stupid prices is one thing, actually getting them is another entirely.

That has been done a bunch in the SS and Stock class drag cars, you try to do it in away that is not real noticebale The human eye can be decieved very easily, the key is to not let anyone with a "stock" car park next to yours at the track with the hood opened I was ask by one of Ma Mopars factory back (1970 Cuda Hemi car)SS/DA racers to take my stock class A/S Hemi 4 speed car, 1970 Baracuda, out of the tech line at the 1974 or 1975 NHRA Winternationals and move it to the rear of the stock tech line, when I ask him why he siad because he didn't want both of our cars to go through tech. side by side at the same time. I told him to take his car out of his SS tech. line and move it back, he didn't want to here that What he didn't know was my car was worst, more illegal, than his as far as missing and moved pieces on the front of my car, someone else had raced it before me and had tried to get weight off the front of the car by cutting and removing some of the stock grill supports and so on The stock E bodys with street Hemi are horrible on the front to rear weight distribution, I finally weighed that turd on the scales at the old Irwindale drag strip several years later, it had around 2160 lbs on the front tires with the car pulled onto the scale up to the front edge of the door and it had around 1280 lbs on the rear tires with the car pulled up so the front tires where off the scale to the front edge of the doors I took that car home after that day and never raced it again A street racer in Santa Monica, CA bought it to street race it It wasn't a original Hemi R code car, it was 383 Baracuda N code car, I think It pays to weigh them first before starting on making any improvements or decisions on racing that car I ended up several years later buying back my old steel front end 415 HP 1963 M.W. Belevedere two door sedan, it had 50.2 % weight on the front tires and 49.8 % on the rear tires with me in the drivers seat That was a good car IHTHs


Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
