  • Welcome to Forever Pontiac

    We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).

    We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.

    We look forward to seeing you around!

We would need a little more information than that to answer with any good advice! 

What kind of Edelbrock? Two barrel, 4 barrel? High rise, duel plane, torquer? What kind of carb? 

What is the intake lift & duration, exhaust lift & duration, overlap?

What kind of vacuum are you pulling at idle & in gear? Do you know?

What kind of torque converter? What kind of 350 6 cyl version or V8? Do you know for sure?

I owned a Z/28 for 35 years. To make a long story short, I put a 350 turbo in from a 6 cyl, than heavily modified it, more clutch an friction plates, a Fairbanks shift kit, (the only one worth putting in), 6 cyl converter. I ran 4 11 gears. It was a 600 hp 302 DZ motor! From a stand still it would not spin the tires! Because in gear at idle it pulled 4” of vacuum! But it was an 11 second car! On the street from a light just about anything could beat it of the line, but after 30 feet the only thing they could see was tail lights getting smaller!

So my point is what is it you what vs what do you really have that maybe you don’t have setup just right!

Universal camshafts are not really optimal.  I've found that custom cams work best for specific engine families.

With that being said, what's your total timing and how quickly does the curve come in?
