Cam RPM Question

Recommended Posts

I have read the cam posts and now I am more confused than before.

 

A lot has been said about the duration and the need to have figures at 50" lift to even get an idea on the specific cam.

Problem is my cam spec is at 75 ".

My cam is a crow

58640

in 40-76 ex 77-41

dur in 296 , ex 298

.75 dur in 214, ex 216

LC in 108, ex 108

lift in 485 ex 495

power range 2200 to 6200 rpm

mild cam stock or near stock engine.

I have just bought this car ,he has recipts for an engine rebuild and SU rebuild and calibration.

The thing is , Driven gently it drives ok smooth etc. But if you put the car in second early say 1500 rpm and floor the car it will smoothly pull but not much power all the way to between 4500 and 5000 rpm after which it pulls really hard to 7000 and that is where I stop reving it.

My question is do you think the cam is timed wrong as It should pull much earlier and run out at 6200 rpm?

Thanks Col
