Just wondering if any of you guys have tried Comp Cams Xtreme energy 274H cam in a 302. I'm running one now and wondering if the cam may be too 'big' resulting in a loss of power or is it my rear gears causing the problem. Specs are 230/236 duration at .050 and 520/523 lift, 110 lsa. I was running the old Crane Blazer 288-2H with 218/230 dur @.050 with 488/498 lift, 114 lsa and the car seemed more responsive with the 'old' cam. Rest of engine specs are 10/1 compression, 4v heads, dual plane intake, 650 double pumper, headers, and 2.5 inch exhaust. 4 speed and the rear gears are 3.00,... So is the cam too much or is it just the bonehead move of not yet having taller gears in the rear?
So..any ideas?? Thanks.
