I have built 346ci with 72cc Heads the compresstion is around 8:5.1 with stock sized head gasket now I'm thinking about going with 57cc heads from TSP with a thiner head gasket for 11+ compresstion is that possible???


Does anybody have any idea what my compresstion will be???



Thanks.

I don't even know what compresstion is.

If you mean compression here are two online calculators that might help:

Are your pistons true flat-tops, or do they have valve relief or dish? If so, how many cc is the relief or dish? With a true flat-top like the OE piston, you'd have over 12:1 with a .040" and 57cc chamber!

I'm gonna hi-jack for a second.

Matt, I have one of your forged 347's with Diamond pistons. I have stock replacement Fel Pro head gaskets and a set of stock LS2 heads. What would my compression be?

What cc are the pistons? What compressed thickness is that gasket?

Thanks for replying Matt,

If I'm not mistaken the pistons have -9cc Valve relief.
