ok so as soon as i finish my rusty body i plan to to a cold air intake and a new exaust system...after that i want to do some head modification work (im working with a redtop) so i would like to get bigger valves and have it ported and maybe have the chambers polished...? ok so before i do all this i need to get my fuel system up to par. would it be eaiser to do a FPR or bigger injectors? depending on which route i go wat will i need to do with the ecu? thanks for the advice and
