I have a 216 220 525 lift comp cam fitted and it has 1.8 rockers with 918 springs.

My car has ported heads at 10.7:1 , BBK 80mm and LS6 manifold.

It has run 11.414/118.6mph with a Yank SS3600 and 3.73s on 235/60 x 15 ET radials. At 3600lb race weight. It also is a daily driver and can cruise at 30mpg at 65mph. The car is making peak power at 6200rpm and peak torque at 5100rpm. It did 368rwhp locked on a Dynolog dyno which is like 422rwhp plus on a dynojet.

I am wondering if there are any other cam choices i could make that would result in better strip performance without losing economy and maybe even pick up better idle quality. It currently is idling well at 750rpm in gear at 46Kpa.

I have noticed the CheaTR cam - which is know i couldnt get due to the 1.8 rockers. But i wonder if i went to something like it with the lift adjusted to get the right amount of lift not to cause piston trouble. Would a cam like this give a performance gain??

Any suggestions appreciated.
