New 1:8 roller rockers, what would my new cam specs be???
Discussion
Hi
I'm considering 1:8 roller rockers so I don't have to tear into the internals for a cam swap, and see they could offer an increase from around .550 lift to .580 , an additional 0.030" of lift at both the intake and exhaust valves.
The piston to valve clearance gets tight with a 1:85 on the 02 + LS6, so 1:8 is as high as I'd go.
I'm hoping someone can fill in some blanks for me so I can compair the rr and the extra power in comparision to camshaft swap gains??
LS6 cam 204/218 duration 0.551/0.547 lift, on 117.5 LSA
LS6 + 1:8 rr __?____? duration 0.580/______ lift, on __? LSA
Small cam 224/224 duration 0.551/ 0.551 lift, on 114 LSA
Medium cam 232/234 duration 0.595/ 0.598 lift, on 112 LSA
Big cam 236,240 duration 0.630/ 0.612 lift, on 111 LSA
I'm still don't have a full understand of camshaft numbers, but if someone could fill in these numbers I'm sure it would put another piece of the puzzle in place for me.
Thanks in advance for the help
