I just reviewed my build sheet that I used when I assembled the engine. I am running a 55 cc closed chamber head. The piston is .006 above deck. .039 gasket. Piston dish is 21. Static compression is 11.27 and dynamic is 8.80. I had the timing set at 34 degrees with my timing light. The tunner said his read 37. I will check my timing in the next day or so with my timing light to verify timing. I am very happy with the dyno numbers considering the air temperature and drivetrain loss. Very loose converter and 4.10 gear. The car is a street/strip car. It's more street than strip. If I can hook up I should run in the 11s.
I am debating on swithcing to a 3.73 rear gear.
