How is this cam NA and with a 200 shot
How is this cam NA and with a 200 shot of Nitrous. It seems to run pretty good NA. Hopefully I can get it to the track next year. I bought these from Crower on sale a while back. I am running this cam in a 455 with KRE aluminum D ports.

274 degrees duration @ .050" lift? 120 lb. seat pressure closed? Did I read that right? That's the "biggest" flat tappet cam I've ever seen.

Jesus...the peaks of the lobes on it must be flat to have that much duration and still provide adequate "ramps" for a flat tappet lifter. The "baby" solid roller I had in the Discomobile was only in the low 260's @ .050".

Back in the 70's I ran a GK SFT cam in my track only SBC that had 280 degrees @ 050. UltraDyne offers SFT cams up to 296 degrees @ 050.

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.
