Quick Compression ratio question... I'm having an argument on a different board, and I need a quick answer: What is the stock compression ratio for a 2002 LS1?

If you're talkin same heads/head gaskets/et cetera, yes it should be the same for all years(LS1 of course). I know somewhere around '00 they changed head gaskets but I don't know if that had any effect whatsover on compression ratio.

. they all have 10.1 compression but the 98-00 i believe had a difference thickness head gasket.
