im doing a 383 on my 93 z28. im going to put about a 175-200 wet shot on it. I already have the comp cam 224/230 cam. The heads are going to be worked a little too. What HP is the stock fuel pump good up to? What is a good fuel pump to use for about 550 HP and what flow do i look for? also should i use 30lb or 36lb injectors? thanks
