I purchased a 91 LX 5.0 5 spd. I just ordered MSD distributor,cap,wires,CAI,headers,catted h pipe,cat back, underdrives,and thats it for now. I would like to add a throttle body,and upper/lower intake as well as a good cam and heads. But for now I think the cam will be the next purchase. This will be a daily driver so I want somthing with a decently stock style idle and somthing that isnt too exotic if at all, just one to make good power. Should I go for the b303? Will this cam even make a big difference or should I add heads/intake first, and if i dont will the cam work with my stock heads and intake? Any help I would appreciate thanks.
