col Posted April 15, 2008 Share Posted April 15, 2008 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 Quote Link to comment Share on other sites More sharing options...
