Does anyone have part numbers or pictures of BBC headers adapted to a 500 for a G Body? or early Chevelle for that matter. I have two sets, neither of which are satisfying the need. One is a set of G Body long tubes and the passenger side is built to totally interfere with the AC box. The other is a set of Sanderson A Body mid length that interfere with the passenger upper A-arm and driver frame. The Sandersons can be made to work but I wonder if a set of BBC mid length or long tubes would be easier to manipulate onto a set of Cadillac flanges. Any suggestions or pictures would be appreciated.
