Is 72cc the largest chambers available for ls1's?? Hey all i just bought an SS 2 days ago with a 402 in it and the heads have been milled to 62cc giving the motor 11.2:1 CR. I was wondering if 72 cc heads are the largest available and what would that lower my CR to? Contemplating going forced induction eventually and would like to know if that's possible with this motor on pump gas, no meth setup. I'm sure i should also post this in the FI section as well.
Thanks!
Thanks!
Can you give us any more details on the short-block? What pistons (part number if you've got it) are they?

Bought in june, 08 invoice # 26105
Bought in june, 08 invoice # 26105 Right on, a GM MLS gasket, 72cc heads, and that short-block will net you right at 10.0:1 static compression. Were you wanting less than that?

well with the fast 90/92 and a properly spec'd cam i'd like to know about where i'd be at through an auto to see if it's worth the while, otherwise i'd consider selling the shortblock and getting an aluminum based one made for boost. John figured 600rwhp would likely be the best i'd see on pump gas through an auto. Not thinking it's quite enough for me to make the switch right now.
