Sounds stout! What are the specs on your cam? Dished pistons, valve reliefs, etc? Any other details you don't mind sharing? Did you by chance cc your chambers after having them shaved 30 thou? Thanks in advance:)

.498 .480 lift with 1.6 rockers
200 206 dur @.050
112 LSA
108 IC
Pistons have a 3.6cc dish
I don't know the exact head chamber volume, but the machinist said a good rule of thumb is a 5cc loss of chamber volume for every .010" of mill.
THat nets me roughly a 49cc head volume.
It is hard to calculate exact compression because I don't know the exact head chamber volume, and our pistons stick about .010" up above the block deck at TDC...Wierd. Desktop dyno says I have between 10.85:1 and 11.0:1 compression.
It still runs fine on premium pump gas. I will have to wait till almost 4000 rpm before the n20 kicks in though.
