I'm building an 83 Pro-street Grand Prix and I want to step up to a roller cam. OK here goes. 462, h-beam rods, TRW forged pistons, currently have #48 heads, opened to RA IV gasket, lots of bowl work, ect., Victor, 850 Holley, Mallory Comp 9000, MSD 6AL, TH-400, 10” 3700 stall, 4.56 gears, spool, 15 X 33 slicks. I used this engine in my 65 GTO with an Ultradyne solid cam, 263/271 dur. @.050, .611 lift with 1.65 roller rockers, 106 centerline. Best time was 11.78 @116. I want 10’s out of the Grand Prix. Glass hood, trunk, doors, lexan, 10 Pt. Cage, not sure what the car weight is. Looking into Edelbrock heads now. I may just buy a set and clean-up the ports myself. Can anyone recommend a good roller cam for such a set up? I was looking at a Crower roller cam with these specs. 312/319 adv. dur., 277/283 @ .050, .421/.433 lobe lift, .632/.650 w/1.5 rockers. Any suggestions? Will this engine require a lifter bore brace and stud girdle? Any help is well appreciated.
Todd

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.
