    To make that much power you're going to need a cam with way more lift than the Vortec heads can handle without modifications. /forums/images/graemlins/frown.gif They probably won't even flow well enough to support that power range, regardless of cam lift. To make that kind of power you're going to have to step up to the plate and buy some good aftermarket heads. /forums/images/graemlins/eek.gif 450-500 HP is asking a lot from a 350.

    jegs has some relatively inexpensive aluminum heads out, but arent cast heads stronger and less prone to warpage?

    Wow...I agree, Vortec's arent going to cut it. AFR's, Brodix or Trick Flows. If your serious about this buildup I would suggest you also post this question on the Team Chevelle board under the "Performance" area.
    http://www.chevelles.com/cgi-bin/forum/ultimatebb.cgi

    Theres several people there with these kind of motors who are more than willing to provide info /forums/images/graemlins/thumb.gif.
