New cam

RoadWarrior · 06-22-2003, 07:59 PM

Well since the clutch started slipping on my car i decided to do a few other things while it was all out. I decided to swap to a new roller cam and replace the old style hydraulic cam. I went with the comp cams extreme energy 274hr-12. With the roller rockers i have it should bring it up to about .600" lift exhaust and about .589" intake. The only thing i have to make sure that i have the clearance with the pistons. I wish i would have got the better forged pistons instead of the speed pro 273 hypereutectic's. But i guess ill find out when i roll the motor over on the stand.

Edelbrock performer 5.0's with the 1.90 valves. They also just came back from the shop after getting ported and polished.

You shouldn't have any clearance problems then. I plan on going with the 274XE. I am running AFR 165's and I have Probe FPS forged pistons, and I was told I could possibly run the 282XE.
