318 chrysler question

Hey all.... I am looking at a 1969 barracuda with a 318 chrysler w/ velvet drive transmission.I was thinking of doing a rebuild on the engine if i buy it. I saw a engine for sale near me. It's a 318 chrysler with a borg warrner velvet drive tranny completly rebuilt with 100 hours on it. Its a 72 yr though. Would this fit in my 69 yr barracuda? It would save me big $$ and allot of time.

Thanks all, Chris

The 69 and 72 318s will both be LM style as opposed to a polyhead. Depending wwhere you are Speed Specialities in El Cajo California already has an LM block bored .60 over. If it were me I would rebuild the original engine unless it was run in salt water.

I would guess that your original engine is obviously a marine engine and the rebuilt used an automotive block for the rebuild. I don't think the blocks were different.

I just talked to the guy who owns the boat and he said when he did a compression test it was around 120 if that means anything. The boats been sitting for two years though and makes me a bit sketchy....   any feedback from any of you engiine guru's.....

Thanks chris

If all 8 cylinders are within 10%, @120 p.s.i, that is 12 p.s.i. difference, it should be O.K.. As for marine, and auto app. blocks, most single engine Chryslers are right hand rotation. This is why you can use a auto motor in a boat. On my Poly motor, the left head is strictly marine. Mainly because of the coolant flow. Be shure to look closely at the coolant hoses and if you can, look at a service manual, for a coolant flow diagram. I learned much needed knowledge about mine by buying a manual.
