If I were you I would call Scott Esterly at Summit and see if he could get you that cam ground on a 112-113 instead of the 110.He is a pontiac guy.I think the Johnson hyd rollers would be a good choice if you could find them.Myself I would use the Comps again.Tom

I would not run those 6294 E solid rollers on that. Those eduramax bushing style lifters are meant for BIG spring pressures on Solid Rollers. I would run a 6924H or the 6260H that have the pressure lubed needle bearings. I would just do the 6260H, not worth the extra money for the 7 grams you save on the 6294H lifters. If you want to spend more money and make it tougher yet have Crower add another oil hole so it oils from both sides of the bearing. On that MILD roller hybrid set up the pin oiled needle bearings will out last the bushings.

You might want to go a little bigger on the specs with the hybrid set up, you loose some duration from the lash.

FWIW...If going with the HR set up I would get it from Bullet cams and run a Morel HR lifter or on of the Johnson Tom mentioned. I think Howard’s and Lunati are both Morels. Could run the comp too though. I think some of the Bullet profiles have a little gentler opening ramps than that comp your looking at and tend to run quieter, call them and ask. From Comp I would do want of the gentler magnum HR profiles if you want it to last and run a little quieter. Still may not be as quiet as some of the Bullets though.

Agree with Jay on the lobe design. FYI, Butler sells it with a 112 LSA.

Since you have to buy the cam anyway, I don't see a reason to buy a hydraulic roller stick, and then put solid roller lifters on it.

May as well buy a solid roller stick at this point and go all the way if you're really hooked on a solid.

Personally, I'd replace the hydraulic roller cam you had in the engine with a duplicate and just run a hydraulic roller lifter on it. Either get the Comp S or the Johnsons and call it done.
