I've been using some compression calculators and I guess I'm not doing something right.. Its way off! First off heres my build
-Ls1
-Stock crank
-Stock 241 heads
-Compstar pistons
-Wiseco pistons... Which ones??

I hope to get around 9.0-9.5 on the compression. I was looking at the wiseco -11cc pistons from Texas Speed and Performance. I'm not sure if they'll get me there. I can switch to 317 heads if I have to. If these won't get me there what cc do I need?? Sorry for the newb question. I know someone here was doing the same build. Thanks
