Thanks to everyone for the info. This is a great resource for those of us that have forgot more than we remember.

I got the same story from Patrick. I've run into it before with a GMC in the late sixties. I had a factory installed engine that was "never used" in pickups. Factories do all sorts of things that are contrary to what they say.

This won't be a stock engine, but it won't be a hot engine either. More your standard 40 over, moderate cam, dual carb 261.

The block will be line-bored, that way if I'm lucky enough to wear this one out, It'll be ready for next time.

Thanks again. joe
