F/I Compression Experts-How much will comp drop on stock LS6 by going to 72 cc heads I have a bone stock D1SC blown LS6 motor making of coure 10:5 to 1 compression because its stock. If I open the combustion chambers to 72 cc how low will this drop my compression down to if I use stock GM head gaskets?
I have heard anywhere from 9:5 to 1 to 9:9 to 1 and want to know what the accurate figure is from those who know FOR SURE!!
My goal is to get my stock LS6 motor down to 9:5 to 1 compression to make it better suited for 10 lbs of boost with my D1SC. Next question, is there a problem if i opened up my LS6 heads to lets say 74 cc or 75 cc, or whatever the amount would be, in order to reach 9:5 to 1 with stock GM head gaskets!
THANKS
