I need some advice about choosing a cam for my car. I have narrowed my selection to two Comp Cams Xtreme Energy Hydraulic Flat Tappet Camshafts.
Cam Grind # XE262H
Operating Range: 1400-5600 rpm
DURATION Valve Lift ( 1.73 Rocker) Lobe
Intake : 262 218 0.513 110 deg
Exhaust : 270 224 0.520
Cam Grind # XE 274H
Operating range: 2000-6000 rpm
DURATION Valve Lift ( w 1.73 Rocker ) Lobe
Intake: 274 230 0.562 110 degree
Exhaust: 286 236 0.565
Which of the above is a better camshaft for every day stop & go street driving at moderate rpms. I don’t track the car at all but, I do get into stop light drag race once in a while and, I want a noticeable idle. I don’t know much about the internals of the motor. It runs very strong with no smoke but has lifter noise. It has an aftermarket cam with a noticeable idle. I run a Holley 650 DP, Mind train headers & mufflers and 4.22:1 final drive. Any advice is highly appreciated.
