how will you come up with 14.7:1? those gotta be some tiny chambers! Lets say hypethetically, If I zero deck, use that small gasket, and end up with a 110 cc chamber what would the compression be? I tried to do the math but it just confuses the hell outta me. So many variables. Would that put me some where in the 9:1- 9.5:1 range? What kinda numbers would you say I could see from this rat? Please tell me I will hit the 500 ftlbs. mark. I appreciate all the info Pat.
