Need help with DCR
I know this has been covered before but I have been searching and just can't seem to figure it out. I'm thinking about running some PP stage 2 LS6 heads with a 64cc chambers. I would like to run some .030 or .040 head gaskets but I can't figure up the CR to see what everything would even out to. Can somebody please help me? Here's my cam specs:
Cam Valve Events 0.006 0.050 0.200
Intake Duration - ID 280 230 154 3016 XFI lobe .612"
Exhaust Duration - ED 281 232 153 3726 XE-R lobe .595"
Lobe Center Angle - LSA 110 110 110
Intake Centerline - ICL 108 108 108
Intake Valve opens - IVO 32 7 -31 BTDC (- indicates ATDC)
Intake Valve closes - IVC 68 43 5 ABDC
Exhaust Valve Opens - EVO 72.5 48 8.5 BBDC
Exhaust Valve Closes - EVC 28.5 4 -35.5 ATDC (- indicates BTDC)
Exhaust Centerline - ECL 112 112 112
Overlap 60.5 11 -66.5 degrees
Other than that its a completely stock bottom end. If someone could help me out here I would really appreciate it.
