Yeah I know this has been discussed numerous times, but why can't I find anything when I search?? I just bought a newly rebuilt head and being that I have 4 NA cams laying around I thought why not just do it. Is there any conclusive evidence that it improves performance? Any info would be greatly appreciated.

Thanks

Mo

Yeah I tried. Maybe I just messed up or something. It wasn't the Doc who did this, you were right. I just spoke to him and he said that it lowers the power band and hurts top end, but it improves low end.

yes and no......i think the bottom line ended up being they are beneficial TO A POINT.....a good early mod but anything past about 300-350hp and you are better off having the turbo exhaust cam in....

which by the way the only one different is the exhaust one...you dont need to change the other one... FYI

:D

I could have sworn it moved the power band UP slightly less than 500rpm, sacrificing some low end torque for more horsepower. I could be wrong though. If I could only find that old link.....

My friend Ti (Poi Dog) did the NA cam conversion on his 88T, and said he didn't like it and really didn't notice any power gains from driving it, so he put his GT cams back in. Just my .02

It looked in that dyno like the NA cams had less low end power before spool, and then had more(but got consistently less) towards redline. What is it about the cams that make them help on lower Hp cars but hurt on higher horsepower cars? That doesnt make much sense to me.
