Mike..the cam is actually ground on a 108 LSA...installed at 105. I'm going to pick up Mike's gage early in the week,and see what I get with it! If I do have 11:1..maybe I shouldn't have Jeff mill them. Thanks!



Randy I did a quick run on some estimated numbers of your engine and came up with a 10.1 comp.

I used
.001 below deck
4.34 bore
84cc combustion chamber
6cc PV
4.5 gasket bore
.038 gasket thickness
3.75 stroke

if this is close to accurate your comp is about right. 10.1 - 10.2
