So far i have a 1989 gt vert with bbk cai, bbk shorty headers, o/r x to flows (no cats), u/d pullies, hurst short throw, full length SFC's, a/c and smog delete and a strut tower brace. I am now looking for a cheap H/C/I setup. I found a set of gt-40p heads (92,000 miles on them) for $200 locally....a cobra upper and lower for $250 and either want to buy a E-303 or B-303 cam. A FEW questions now....as the title says, if i do all of the work involving a H/C/I swap i want to be happy with the result, i know gt-40p heads aren't aftermarket but still hear good things about them, would it be worth while to go ahead and buy/install them or should i keep saving for afr's,patriot's, eddy's, or tfs's? NEXT question is which cam? im leaning toward the B but really have no clue....as far as goals im just looking to have a nice street cruiser/rare test n tune at the track. No clue what this would put out but 300+ would be really nice! Next would be RR? size? 1.6? 1.7? brand? Once again no clue please teach me!
