cracked block 318

Don't give up looking. They come up on eBay and various other spots. I had to buy a whole boat for mine. Good luck.

I have a 318 I might consider selling. It is out of a 70 Wildact that I bought a few years ago. PO started a restoration and never completed. He said it ran, thats about all I know about it.

What part of Indiana you from?

im from warsaw in northern indiana , what would u need for the engine trying to stay on a budget on this project , thats why i was asking about the difference in auto vs marine my crank and cam is still good so i was just thinking about changing enternals but i dont know , im not in a big hurry i have other boats to play with so i can keep looking

See my post earlier tonight on a different Mopar thread for a lot of other introductory Chrysler wisdom. I won't repeat all that here.

All 318 blocks are NOT the same. If you're trying to use a late-model block with a roller cam, you're out of luck, UNLESS you can find a suitable cam blank and someone to cut it into a reverse-rotation cam. Crane Cams did one for me for about $800 before they went bankrupt. Somewhere the man who knew enough to do that for me still lives... The cam is the one essential barrier to a reverse-rotation roller cam marine motor that you can't source anywhere besides "custom manufacture". Not a budget item.

However, the good news is that pre-roller cam auto blocks will work just fine. I did notice that the engine mount ears on my marine block are different. I think there are more bolt holes on the marine block. But that's not a material difference. I'm just missing a bolt on my current block. The material differences between marine & auto Chrysler engines are mainly auxiliaries, not the block. The front cover is different. The intake & exhaust manifolds are different. The carb & alternator are marine-specific. The starter & flywheel housing are marine specific. The oil pan is a marine pan. But those are all things that attach to the block, not the block itself. So are freeze plugs. Go find an old carbed or throttle-body-injected block in good shape and use it.

By the way, where are you?

And my first CC was a '69 318 Barracuda not so long ago.
