Which Cams?
From everything I have read so far concering the best cam choice for an SC with CIS the 964 cam grind is the most mentioned. Today while doing some more research I stumbled across an article which mentioned Web-Cams no not the ones where you go online and look at other parts of the world. This a company in Riverside California who manufacture and re-manufacture racing cams.The article mentioned that their 20/21 grind as it is known is the best cam for use with CIS and standard igntion giving best mid to high range power! Does anyone know this shop is anyone running 20/21 cams and if so what the opinion on them?

My only beef with Web Cams is they often hard weld cams and regrind to spec. Not a good way to go.
The 20/21 is the same as a DC19 and is a cheater regrind of an SC cam. Most folks say they 964 is best, but don't mention this is strictly among the stock cams. There are lots of cool custom grinds for common plenum cars, including the 20/21, DC19, DC20 and DC21.

I ran the web cam 20/21 for decades in DE on a 9.8:1 3.0L SC with SSI and stock muffler. Excellent torque and strong throughout the rev range. Would pull well to the rev limit in 4th (6850RPM) on the back straight at Watkins Glen. This set up also returned 26mpg on the highway. I highly recommend Web Cam.
