RE: 427 marine, bored .020

A sonic check is the only way to know for sure. You will have to have custom pistons for anything more that .030 over.

I can't relate to the 400 hours in terms of wear. If it's 400 of power boat racing its probably got a lot of wear. If its 400 of pulling skiers it may be fine.

You could try a leak down test. That would give you some idea of the ring seal. If they are OK then it may not be wore very much.

This thread, so far...
