[J/SA Grand Prix]

Thanks alot for all your replies. My dad and I are building a 400c.i 300 horse motor. This sucker calls for the 96 cast heads, which are on my bracket car right now. It wants the #481733 intake and the rochester 7041263. Only reason behind building the 400 instead of the 455 is that it would be alot safer to turn her 7200 - 7500 and its rated 25 h.p less than the 455. We also have every original part laying around. What motor/application of pontiac did you build? I'm interested in all pontiac stockers! funny thing is, the 71 grand prix has the 72 grill on it! lol. speaking with Jerry Hefler he told me Xeno or Zeno in arkansas builds a hell of a qjet. I'm wondering what tricks i could use to get her about 7-9 tenths under at atleast qualify than looking like a bunch of idiots! lol
