The Stump Puller comes in at 230/236 and the Old Faithful comes in one step higher at 236/242. While both are usually on a 112° LSA, there is enough difference that operating and performance goals should be considered before making a choice. Iron heads and the SP seem to go together well and a little better for tight converters. I know that Dave Bisschop usually recommended the SP for mild builds with iron heads.
Everybody copies everybody on cams and it seems that even the local deli probably carries a reasonable copy of either cam profile -- but I would suspect that SD Performance would still be selling cams even if it will be awhile before his shop is up and running.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
