comp vs. crower camshaft
long story short, i ordered a comp, the guy jerked me around for a few weeks until he got me a crower. im wondering which is better.
Crower camshaft:
Advertised Camshaft Specifications: COLD
INTAKE: Duration: 319degrees Lift: .429 Clearance: .006
EXHAUST: Duration: 310degrees Lift: .436 Clearance: .008
The information below is for degreeing cam only. Correct only at .050" tappet lift.
INTAKE: Opens 12.5BTDC
Closes 42.5ABDC
EXHAUST: Opens 44.5BBDC
Closes -1.5BTDC
Lobe separation: 109degrees
Duration at .050" lobe lift:
Intake 235degrees
Exhaust 223degrees
Intake .268
Exhaust .242
RPM Operating range: 900-7,500+
Comp camshaft:
Valve setting:
Intake .007
Exhaust .009
Duration:
Adv.
Intake 256
Exhaust 268
@ .050"
Intake 220
Exhaust 216
Valve lift:
Intake .456
Exhaust .428
Lobe separation angle:
Intake 107degrees
Exhaust 111degrees
RPM Operating range: 2,000-7,200+
Im not entirely sure what all the numbers mean but i believe the crower is better as it has a wider rpm operating range. Could anyone tell me which one would yield better performance?
