RAIV cam w/1.65:1 rockers is a popular choice for 455s. So is a Crower 60916 with 1.5s or 1.65s. A lot of guys run a Comp XE268 or 274 series.
If the heads are unported, stick to .470-.490 lift with .230-240 duration @ .050". LAS should range from 110 to 112. This will wake up that 455 and your client will have a big fat torque curve to play with! Plus about 400-430 hp!

The HO cam (068) will be the best choice on this level.

Summit 2801 is a new and improved 068. Use it with confidence.

Summit K2801 is the best value on the market. Dyno results between camshafts with similar specifications (like the K2801 and the Crane H 272-2) are nearly identical...Robert

And what about the 2802 on a car with this set up? That's with the 1.5 or 1.52 rockers?

Come on, with a/c, stock exhaust, #s matching car (carb ect...), doing a frame off #1 resto. for a customer, why would he want more than a 068 HO cam?

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.
