455 hyd roller cam?
Hi everybody,
Going thru my old parts stash a found a comp hyd roller cam with a 3315/3317(230/242@.050”) on a 114 LSA grind. How would this work on a 455 with 9.8:1 CR and ported d ports? Thanks, Kevin |

Very similar to Butler custom except with an additional 6 degrees exhaust duration. They are COMP XE lobes.
https://butlerperformance.com/i-2936...tegory:1459686 It's the Comp XR288HR but instead of a 110 LSA its custom ground with the wider 114 lobe separation. .

I`d run it. Especially in a heavier street car.

Should make great power, have decent vacuum and a steady idle especially with a 114 LSA. If you have an auto trans it should have a 2500 stall converter for best performance.

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.
