well im shoting for between 9 to 9.5 to 1. ive got a low comp motor right now (8.5 to 1) i hate it, makes alot of power but it takes to much work to get my truck out of the whole with out footing it. lq9 4 bore on a 4 stroke with a diamond -28 cc i think 64 cc puts me right like 9.2 or 9.3 with it .005 out of the whole.

 

Well the pat stg 3 is 68 so comp will be lower then that.. you need a small chamber or run a thinner head gasket....

 

patriot makes 2 or 3 stage 3s i know they make a 64 and a 59 cc stage 3
