I just bought an correctly dated 1966 360hp engine. My mechanic says it's bored out .060 over. He doesn't seem to think that it's a problem to take it out .070, and get special pistons, etc. What do you guys think? It's not easy getting this engine, but should I just scrap it, start over and write it off to education?
Thanks,
Bob

Have the cylinders sonic tested it might be a keeper.

Unless you are putting together a resto car it's a boat anchor, too much work and expensive for V-8 chevy.

Bob Most early rats will go 100 over without problems but as Carl suggested have it sonic tested. It shouldn't cost that much. We check the bores for $80 if it is clean.

OOOps,B/B 360HP? I thought we were talking about something else.

Thanks guys. When my mechanic was telling me about the engine he pretty much said what you guys are saying. He showed me how thick the walls of the cylinders were and said these old engines could go out a long way. He also said if it wasn't for the dates on the engine it would be a boat anchor. I am restoring the car. How much should it cost to do the engine?
Thanks,
Bob

A newsflash from my mechanic: The heads are standard. The measuring device he used first was defective. He said he wondered why the pistons looked like regular Chevy pistons. Thanks again, for the info which I think is important to know.
