Call Quillen Motorsports Engineering (256-476-1053) and Travis can fix you up with a first class camshaft recommendation.
David Butler (Butler Performance) could probably have it ground for you fairly quickly thru his company. (The Butlers: David and Rodney do a lot of joint projects with Travis on boosting pontiacs. Tom V.

I've not designed any cams for turbo Pontiacs, but have done several for LS motors. The September 2014 issue of Car Craft has an article that mentioned some of them. Some of my cams with intake durations in the lower 220's that have made 700+rwhp.
All have been fuel injected though, so I don't know how well my designs would work if you are using a carb.

Lee, are you talking (Ultradyne) Harold B type "Profile Designing" or are you talking picking durations, lifts, and centerlines?

Tom, NOT "profile designing"!!! Harold Brookshire is one of my idols, and I really wish I could have been able to meet him in person.
There are so many quality lobe designs available, I determine what lift and timing events I want for a cam, then find lobes that provide the best fit. Between CompCams and Bullet, I have always been able to find existing lobes that fit my needs, then they grind them for me.

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.
