Off the shelf type designs. I know most anyone will make a custom cam, but I am looking for something from stock.

Noticed the Comp XR288HR shelf grind.
Spec's: 236, 242 .050 duration, .520, .540 lift, ground on 110 LSA. Seems a little bigger than the old Comp 280. Anyone use this hydraulic roller in a 462-474 with moderately ported (250 cfm) heads??? I am limited to 9.4 C/R, (milled 197's). Car is 3480 lbs (w/o driver, 3695 with). Turbo 400 & currently 3.55's. Current plan is to go custom convertor, taller slick & more gear.

I didn't see them online but in their catalog they are listed under part numbers 289611, 289621, 289631 and 289641. Called the PowerMax hydraulic roller. Durations range from 214/222 up to 242/252. Two smaller cams have 112 lobe sep and two larger 114. Lifts range from .488I to .558I with 1.5 rockers.

Hey Pinon Head, I used the 288hr in my 76 GP last season. I was running a little more compression than you but the cam was great for my 462. I was consistently in the mid to high 11's and my heads didn't flow that well. I raced while other guys set valve clearance. This year I opted for a little more cam so I guess I'll be settin valves more often. I think the HRs are great and if I had a streeter I would use them exclusively. Just my 2 cents.
