I have an f303 in a 347 that runs 11.80's, the frpp cams do ok for what they cost. the b303 would pick up the car a bit....but if your gonna pull the intake and front cover for the cam...might as well look for some heads too. FYI 1.7 roller rockers will take your stock cam to around .480 lift with out nearly as much work.

I personally would not go to the hassle of changing a camshaft to put a used grind in- you can get a trickflow stage 1 (221/225 @ 0.50 .498/.510) for like 150.00 if I remember correctly which will make a nice lopey idle and the accompanying light surging and lack of power below 3000- above 3000 hang on.

 

I would go with 1.7 rockers and a stock cam if I were you as a first step.
