Post Finding a V8 Chrysler engine and transmission for a"48" Plymouth Business Coupe?

Can anyone out there give me some advice or suggestions on the best Chrysler V8 engine,
transmission,and rearend that could be dropped in
my "48"Plym.Coupe using the original frame and suspension system.Please keep in mind,I'm on a working mans budget looking for the simplest and best bang for the buck.
What would be a good choice in a Chysler or Plym.
4 or 5 spd.trans.and what axle is the right length.
Thanks:

Lots of good choices, all of which will fit.
The 318 is probably the most readily available, and the least expensive.
340's are more powerful at about the same weight as the 318, but are getting hard to find ($$'s). 383's are almost as available as 318's, with much more torque and power (standard equipment in the famous Roadrunners).
440's are even bigger(inside and outside).
Any hemi is big and heavy, but has a special attraction because of its design and potential. They don't serve as the basis for all of today's top fuel dragsters and funny cars for nothing. But parts & maintenance won't be cheap.
My personal choice for my 41 Dodge (same frame as yours) is a 383 with a 727 Torqueflite automatic (both are bullet-proof) - reliability means something.
There is an excellent article on these V8's in the May 2002 issue of Hemmings Rod and Performance Magazine, by the way.
Good luck.

I put a 68 plymouth 318 in my 47 Desoto which is basically the same frame . Pretty easy installation. I didnt use a standard tranny I used a 904 automatic, just because I didnt want to mess with linkage stuff. I even am running the stock rear end seems to be working ok. This is just what I have done and it didnt cost me an arm and leg, Good luck

273's are underrated but hard to find. I'd look for a 340 or a 273, there's hi-perf parts out there. If you want to spend a little more money, look for the Red Ram motor. Torqueflite trannies are hard to beat.

I'm assuming the Magnum you're talking about a 360 small block. If that's the case then any of the small block bellhousings will work with any standard trans that was used on small blocks. Or if you prefer to go with an automatic, you can use any of the small block compatible torqueflights, including the later overdrive units.

Use a small block its tough enough squeezing that in ...only minor refabing the right inner skirt to make room for the pwr steering,the headers will give you a little grief but not to bad..and the firewall needs to be recessed about 4"

Actually the guy who asked the current question asked it yesterday. That's the only reason I replied. It would have been better if he had just started a new thread instead of asking his question in the middle of an old one but none the less he has received some good advice.

Earlier in this (old) post there was talk/recommendation of using a 318 for the transplant......thought I would add this , there was two articles in Hotrod mag on getting like 400 HP out of a 318 on a reasonable amount of cash......Think it was called "Junk Yard Jewel " series , had some very good info ,should be able to get the info tru their archives.

I'm not sure about putting the new hemis in a 46-48 plymouth but I've talked to someone that knew someone that did it with the old hemi and the fenders have to be cut to make room for the valve covers.theres not much room in there even without the inner skirts. But ,Where theres a will theres a way...Believe it or not the small block chevy fits much easier than any motor.I have a 68 383 /727 combo that I plan on using for my other biz coupe project ...it looks like a very tight squeeze.

The new hemi is a lot smaller physically than any of the earlier versions. Its about the size of an LS engine with just as much potential. Personally I try to stay away from engines that require a computer mainly because of the cost of all the ancillary junk that goes with it. Pretty hard to make one look good with all the coils hanging on the valve covers and a mile of wiring running all over the place..... and don't even get me started with those stupid engine covers. They look God awful on any engine.....including custom made units. If you have to hide the engine, then what really lies under that cover.
