Re: doug herbert camshafts any good?
I had used 2 cams from Chet Herbert back in the 60's and 70's. Both were right on the money as far as I could check them. Both worked well for my usage. One was SR, the other Hydralic flat tappet. In my opinion, Chet is "The Cam Father". I believe he ground asymetrical cams before anyone else, and his grinds were copied by many and claimed to be their own. I went to Chet first for my cam, but he said he didn't feel comfortable grinding a cam that would be used for the Rochester injection. Since the Rochester is somewhat dependant on manifold vacuum, Chet didn't want to be responsible if my car didn't run right with his cam. I ended up getting Harold's UR10/UR15 from Lunati, which I have not installed yet. Present cam is a street roller from CC. Although it's a roller, it's not agressive enough for my taste. Harold seems to think I will pick up about 20 ft. lbs with his grind, with better idle, and pull harder at higher RPM. Sounds like the magic cam to me.
Still, Chet makes good stuff. If you are wanting to see how your car will run with a roller cam, Chet will get you into one cheaper than anyone else.
I obtained my present Comp Cam in a warrenty dispute 15 years ago. That's why I used it first.
