Found two possible engines, Need advice!!

[Beatles65]

A fellow Plymouth owner on this site has two engines that would possible work for my 1948 Plymouth P-15 Deluxe Club Coupe. What he has is a 1953 Plymouth flathead 6 engine that has about 70,000 miled on it and was told upon purchase that it ran good. It came out of a 3 speed car with overdrive. He also has a 1948 Dodge Falthead 6 engine that is running and has about 40 to 50 thousand miles, but it had fluid drive so he is not sure because of that, if it would drop directly into my car without modifications. He also said there were short and long flathead engines for Dodge so that could be an issue also. What do you guys think about these two engines? Will either of them work in my car?

Thanks for everything from Nebraska, Andrew.

Either will work fine. I'd go for the dodge its a 230CI instead of a 218(assuming both were original to the cars listed) and has less miles. Now if the OD is around grab that.

Sorry. The od is in my plymouth. Is the back of the fluid drive crank different than the manual 3spd?

[Young Ed]

Yes it has 8 bolt holes instead of 4. Should be able to just ignore 1/2 of them.

Yes.......when installing a Dodge engine with a Plymouth flywheel, you

have to attach the flywheel with bolts and nuts (preferably grade 8).

It will work just fine......I ran a couple different Dodge engines in a P15

with no problems.

The longer engines are found in the Chrysler and DeSoto cars.....they are

25 inches long, vs 23 for the Plymouth and Dodge.

You may have a problem with the pilot bushing. On the '47 Dodge fluid drive engine I installed in my '41 Plymouth, the crankshaft was not machined to receive the regular manual transmission pilot bushing. I had to machine the outside diameter of the pilot bushing to get it to fit.

You will have to use the Plymouth bell housing,flywheel, clutch and transmission. I would not try to run anything but the Dodge engine in your car if it was me.

The 230 CI Dodge engine would be my preference. Were it me I would also disassemble, inspect, and rebuild (as required) any engine prior to installing. Much easier to do it on the bench (or stand) than in the car.
