The first thing you should do is e-mail Wesley Roberson or Bob Lang and ask for 10 horsepower back, just like the '72. There's only 3 cc's less volume in the valve reliefs, so it should be the same, or you can put the #485912 intake, and 7M5 heads on it and call her a '72 Grand Prix. That way you get the 315 h.p. rating. Then you got to get in touch with Todd Hoven, he's been working on his '72 GTO with the same engine, thing really screams. I'm sure he'll help........................
