Pushrod length question/suggestions Have a stock 6.0 block, 823 square ports milled .040 & .040 cometic head gaskets. 4.030 mahle flat top pistons with -4cc valve reliefs for the l92 valves.
1. What will this give me as far as compression?
2. What length pushrod should i run?

Well stock ls3 heads are 68cc I believe. Every .006 milled is 1cc
So thats about 61.5 chamber.
You should ALWAYS measure for pushrod length
going by this calculator your quench is .072 which could be a lot better, and static compression is 11.51:1. now thats probably close, but your piston in hole and deck height play a role too and i got no idea what those are for your car.

Im just using a compression calculator I found on here. Go to google search ls1tech compression calculator. Using tbe standard numbers already in tbere and changing what we know about his setup thats the numbers youll get. Thats why I said it wont be exact because we dont know the details like deck height piston out of hole etc
