Re: Engine gone bang !

Sorry about your news.

Two things that need to be done - establish why it went bang to begin with, and only then how to repair. Pistons rarely just "break" - they get overstressed for some reason first - could be over-revved at some time, over heated, wrong clearances, detonation, etc.

Most types of blocks have a "recommended" max overbore - I can't quote chapter and verse for your specific one, but I have seen engines out to +.060" when everyone said +.040" max. It may well depend on cylinder wall thickness on your particular block. And the availability of oversize pistons.

How many miles on this engine?
