Thread: Cam Help for 502 Chevy

    Cam Help for 502 Chevy

    I am building a 502 gen VI for mud racing. I am using a '80 fullsize blazer. I plan on using dominator flange Team G with a 1050 dominator. It has JE pistons, forged crank and rods and plan on Brodix RaceRite rectangle port heads milled to 110cc. I expect around 10.5-11.0 to 1 compression. I am looking for some solid roller cam specs to reach 700-800hp. Hopefully, I am not out of line with my expectations. Any help would be much appreciated. Thanks

    cam

    You should get a custom ground cam.The companies to check with would be Cam Motion,Erson,and Bullet.Where do you race at.

    Can you use a different intake besides the Team G?

    502 cam

    I can run any intake. I thought I would run the Team G because it has a broader RPM range than the others. Any suggestions?

    intake

    I would use a victor or super victor intake and go in and clean up the rough casting and gasket match it.You need to research between these two intakes to see which one would be best for the 502.

    here is a pump gas 502 made into a 509, that I built for a local guy. It was a gm perf. 502/502 core engine, and thats exactly what it turned out to be. So, we threw away every part, except the block, crank, and head cores, which are 2.25 intake valve edelbrock Perf. Rpm oval port heads that say GM performance parts. Not bad, $7500, 1 year, and throw everything away. But anyhow, with a fairly radical port job on those heads, and a 270-278 at .050 solid roller on pump gas, with a Victor 4500, and a 1050 carb, it made 735hp and 650 ft/lbs.

    If you ran more compression, and the heads you have have more potential, it could make a lot of power. Where are you located, I am in St.paul,Mn, I noticed you said you run in Mn. If want any further details, let me know

    I am located in Bismarck ND. My head choice might have changed to a little bigger head, Dart Pro 1 or Brodix BB2 plus. What is your preference? What are all the specs on that cam and also RPM range?
    Thanks

    heads

    If your engine is going to be naturally aspirated and you run a heavy truck and you are buying as cast heads i would go with the Pro1 325.
