installing a nailhead in a 41 plymouth

i have a 1941 plymouth business coupe.i'm looking to install a v8 under the hood.i'm not looking to put a clip into the car or even update the front suspension.
looking to rebuild the car as a custom stock...nothing to crazy.
what i would like to do is find a early 60's buick as a Donner car,swap out the eng. trans & rear.
i plan to update the brakes and electrical systems.
there are easier ways to do things...this i know.
i have a certain vision and aesthetic that i would like to follow.
can anyone out there point me into the right direction??
or am i daydreaming??

You should be able to do it. You need to find a donor car and pull some measurements. The rear end may be way too wide. if you want a manual trans, you'll have to figure out linkage for that also. Basically, you can make anything fit with enough custom work. You just need to dive in.

Biggest problem with sixties Buicks is the use of torque tube drive. Buick used them into the late sixties along with the Dynaflow trans. NOTHING (other than Buick) is compatible with the torque tube system they used. The trans isn't a perfomer either. Go with something later than about 65-67 if you use Buick.

Trans adapters are available to mate all Buick V8's (53-64) to the GM TH-350/400 automatic trans so don't worry about using an earlier nailhead. Check out this link for one supplier.

Putting a nailhead in an early Plymouth would definitely be different and I'm for putting anything in anything as long as it's not another small block Chevy.

Good luck with your project.

Buick stopped using the torque tube in 1960 and the dynaflow in 63. After that the ST300 (2 speed) and the ST400 (a TH400 3 speed) was used up to 66 with the nailhead.

The biggest problem I could imagine with the Plymouth is that it was an inline six and the engine compartment probably is going to be to narrow here and there. The starter is on the left side on the Nailhead and it often is in the way of steering components.

Start a journal, we like everyone's build. A 36 Plymouth is a beauty.

another coment.

Since this has been reopened, buick nailheads have the driver's side cylinder head ofset to the rear. opposite most engines , this can sometimes cause more steering gear interference.

I think an early Buick or Cadillac engine in your P2 (Deluxe 6) '36 Plymouth would rule. Don't be shy about offsetting the engine to the passenger side of the engine bay for steering/exhaust clearance. Just be sure to pay attention to the driveshaft alignment.

If the six is still tight I'd be VERY tempted to dress that little bugger up w/a dual carb intake, split exhaust and a little chrome (if done tastefully)- then drive hell outta it! lol

For a V8 you'll need stiffer front leaf springs and a completely rebuilt front end including brakes, wheel bearings, etc. In fact I'd be looking to improve the front brakes to a larger drum or possibly discs. Definitely swap to a 2-pot master cylinder. Gonna need a stronger diff, too, w/a gear ratio more suited to cruising (if that's what you're gonna do w/it).

I'd try to keep the stock wheels and caps- they look righteous IMHO. Maybe widen the rears a little. I think the stock wheels were 5" or 6" wide by either 16" or 17" depending on the model.

What about swapping in a slanty? It'd have plenty of cool factor and all MOPAR to boot.

FWIW dep't: My Mom drove a '35 Plymouth PJ 5 window coupe as her daily driver for quite a few years in the '60s. I loved that car! Little 201ci ~85hp flat head 6 w/a floor shifter about 3' long. IIRC it had the floor starter switch. The brakes were a little weak even after being rebuilt but other than that it was a sweet ride.

Forgot to add, an early Hemi would be killer, too. I'd like a 392 (very hard to find and expensive as hell), but a 331 or a 354 would be almost as good- and better in some ways (a little easier to find). Heck, ANY of them would be nice.

The *WOW* factor would be off the charts and the fun of driving it would be, too.

If you are keeping stock suspension ,think about a 340 or 360 the 340 will produce more hp,But the 360 has more torque much better gas mileage easer to find and Much cheaoer and its a Morpar ,these are probably as lightweight as anyother engine and small package ,Easy to install ,Just my opinion for what its worth
