You can talk to Tim Goolsby at Ultradyne/Bullet about exactly what your needs are. He is tough to get in contact with though. Just keep trying. Morning is best. Your biggest challenge is going to be finding a cam core to grind. I just a week ago ordered one of my favorite mild cams from them. 276/286 on a 112. That's a nice cam and makes good vacuum for power brakes and good torque for a heavy car. A custom grind I had made for my old NMCA 4500 lb. car was a 276/284 on a 113. NMCA had a minimum vacuum rule in those days and this cam just made the grade. It propelled that heavy boat to 108 MPH trap speeds with a 421 back in the 1980's. Rules required stock heads, intake and exhaust manifolds. Enough for a class record. I have had good luck with Crower cam saver lifters. The extra oil on the lifter foot certainly doesn't hurt. Good luck with your engine.
If you have some old Pontiac cams, he may be able to re-grind one to meet your needs. Finding a new core is difficult and it looks like there may not be a new run of them by CMC for 2 or 3 years if ever.
