230 crank & rods in a 218 block?

[Loren]

I have a 230 engine with some serious cracks in the block and a 52 218 engine.

I’d like to double check to make sure I can put the 230 crank and rods in the 218 block.

Any thoughts?

crank offset Dodge to Plymouth....?

[Loren]

Actually it’s a Plymouth engine the serial number starts with a P

Believe it’s in the 55-56 era. It also has a harmonic damper.

No problems using the 230 crank etc in a 218 block. Just did the same thing.

Thanks to you both!

I gave it another “look see” and it’s serial number starts with P26 which would indicate a 1955 Plymouth.

The crank has a forging number 952068.

I’ve decided my 52 block is in good shape and it’s the original and the title has the engine number as the VIN ( which I intend to correct ) so it seems like the right thing to do to overhaul it and replace the crank and rods for a power boost.

I have a new old stock Bendix-Stromberg WW carburetor and the Power-Pack manifold for it as well.

Very exciting!

230 and 218 same bore. Use the 230 flywheel and you'll be golden

Loren keep us posted on your progress. That should be a good build.
