That's why I'm afraid to pull my head off. I would really hate to find my pistons trashed.  Mine is using some oil too and had considered opening it up to see whats going on inside.

It was called World War II.

 

Materials such as aluminum and chromium were needed for the war effort, thus cast iron pistons and painted trim instead of chrome on 1942 models.

 

After war the 1946 models went back to aluminum pistons. 

 

The "light weight cast iron" line was used probably to quiet those who would question the use of cast iron pistons after so many years Plymouth bragging about their light-weight aluminum pistons.  Remember Chevrolet used cast iron pistons into the 1950's on their "Cast Iron Wonder" six cylinder engine.

I would say the change in piston material was due to the USA entering the War. Aluminium would of been needed by the military.

I was offered a running 1935 Plymouth engine yesterday to install in my car until I can find a  main bearing cap and get my engine rebuilt.   I know that the '35's had floor shift trannys.  What would it take if I do decide to get this engine to convert it to fit my transmission?

Thanks,

Bob thats easy. Just bolt your bellhousing etc to the 35 engine. As far as I know you shouldn't run into any issues between a 35 and 40.

That is my understanding too. Actually, you should be able to just bolt in a '33 or '34 engine too.

I found out last evening that the engine I am interested in is a '35 Dodge engine instead of a '35 Plymouth engine.

 

Is that going to make a difference?

 

Thanks.

Tod the 33/34 engine won't bolt in. The changed the water jacket from 35 on so that will work. Look about halfway down.

Yes, it you want to put a '35 up engine into a '33 or '34 you have a problem. But you can put a '33 or '34 engine into a '35 and up.
