A good cam is allways a good cam, it just depends what your using it for! Cams have come a long way in the last 20 years.
And it's got alot to do with rollers rockers and roller lifters the quick rise and fall of the cam lobes, where they could'nt do that with a flat hydraulic lifter. Nascar,from what I understand are not allowed to use roller lifters so they use a mushroom lifter. This is wear the bottom of the lifter is a wider rounded end so you can run a much more aggresive cam,with out tearing up the cam or lifters. Now with all the computer simulators, it's alot easier for a cam maker to see just how a cam will act, before he builds it. They can now figure out how high to lift a valve or how long to keep it open before closing it for the best horse power. Alot of cams now run smoother and you don't even know your in trouble, till you see the guy pulling away from you. But I like the older lumpy cams,
they run good and the best part they make every one turn thier
heads to see what just pulled in. HE! HE! HE!
