addicted2dunes Posted June 17, 2011 Report Share Posted June 17, 2011 I was wondering if it was possible to fit a big block in a 1950 Plymouth P20? I mean without major modifications, I know I will modify the steering, no problem, but will it physically fit in the frame rails and between the inner fenders? Thanks guys!

faucet47custom Posted June 17, 2011 Report Share Posted June 17, 2011 Someone had posted about this a few months ago. There is a gent on here that put one in his p15. I would think that would be similar to your p20. Do a search for DNDrodshop, I believe it's who posted that. Quote Link to comment Share on other sites More sharing options...
addicted2dunes Posted June 17, 2011 Author Report Share Posted June 17, 2011 I saw what I think you are speaking of: http://www430.pair.com/p15d24/mopar_forum/showthread.php?t=15143&highlight=bigblock I found a 440 big block and was just in a debate wether I want to do that over a small block, dimensionally the big block is 1/2" longer, 4.5" wider at the valve covers, and 1/2" shorter than a small block, so I think it'll fit. Exhaust will be fun though. Quote Link to comment Share on other sites More sharing options...
faucet47custom Posted June 17, 2011 Report Share Posted June 17, 2011 The extra width isn't a big deal due to the tapering of the inner fender wells, it's widest at the top which gives enough clearance. That can be seen in the pics from DND. I'm looking for a Mopar V8 to plug into my D24 so I will be doing some of the same mods to get everything to work.

Scruffy49 Posted June 20, 2011 Report Share Posted June 20, 2011 Heck I've batted about putting one in a B1B truck. They kinda fit the trucks. Fit pretty nicely in the cars. I'm eyeballing a 54 sedan for sale in the next town over, have a 413-3/727 in the motorhome. If the motorhome leaks I'm putting that monster engine in something around here. I'm leaning toward the sedan over the truck though. Helped a friend put a 383 in a 51 Dodge coupe, 50 Plymouth can't be that much different can it? You really want to find a complete donor car though, you'll need a lot of the little bits that add up quickly. 60s sedans are still cheap, you'll recoup most of the investment selling the front end to someone with a wagon or 2 door.

cwcars88 Posted June 21, 2011 Report Share Posted June 21, 2011 Do they make center dump exhaust manifolds for the 440, if so what are they on. Thanks Wayne Quote Link to comment Share on other sites More sharing options...

dezeldoc Posted June 21, 2011 Report Share Posted June 21, 2011 STAY AS FAR AWAY AS POSSIBLE FROM THESE!!!! I bought a set a few years back and what a bunch of Chinese junk! they do not even fit the heads they are about 1/2" to long, and no way to get the bolts in, not even if i had drilled out the holes. on my 48 i used a set from a "B" body and they fit fine.

Merle Coggins Posted June 21, 2011 Report Share Posted June 21, 2011 I finally found the pictures I had of Ed Gross' (dndrodshop) P15 with a 440. It's a nice lookin' car and I assume it drives quite nicely. Quote Link to comment Share on other sites More sharing options...
HughForrest Posted June 21, 2011 Report Share Posted June 21, 2011 My swap list says the big block is actually 1/2" shorter at 29" than a small block at 29.5". This is as measured from w/p pulley to rear mounting surface. The 440/400 equipped trucks used a center dump exhaust manifold. It interchangeable left to right if you don't care about the heat riser. I've been looking into this because I have a 383 at the machine shop that will go into my '38 Chrysler this next winter. Quote Link to comment Share on other sites More sharing options...

Young Ed Posted June 21, 2011 Report Share Posted June 21, 2011 Not as far but it was in my driveway too. Excited to see his next p15 project on the road. Quote Link to comment Share on other sites More sharing options...
