Hey guys, Just dropped off a 390 block to get cleaned up and bored .060 over which will make the bore 4.110 I believe. Which sized pistons and rings will I need to buy to fit this new bore size? Do any of you know a good website where I could buy these things? Thanks for your help, Jake.

 

Summit racing, jegs, and there are a few other out there too.

You just say 60 over 390 pistons. Your not doing some crazy rod ratio or compression height deal.
