I'm building a 347 for my 86 GT and need to know, what I need to do to my fuel system to match the increase in air flow from the trick flow street heat intake and trick flow TW heads? Injector size? Fuel pump output? I have an adjustable pressure regulator also, still in the planning stages so I'm trying to get everything lined up before I tear into it.

a 255 lph fuel pump, fuel pressure guage, 24lb injectors and calibrated
mass air meter

might want to go a little bit larger on the injector size... I would say 30# or larger. Guys use 24#'ers for h/c/i only, and your increasing the displacment.... but the 255 pump, and calibrated mass air are correct

Just a recomendatoin, you could probably do with a better intake.... Talke to woodsy over at www.fordstrokers.com he know whats up!

NOT AT ALL FOR A WELL BUILT 347 a well built 347 needs to breath and once it can breath it needs to be fed adequately!!

wont matter if he runs a wet kit

wet kit? I was told I have a speed density system, so do I need to change it or do they make something that is adjustable? Not familiar with the system, thanks for the help, going with the 255 pump and 30# injectors for sure.

yes what you need to change that is non adjustable is your speed density system and convert it to MAF.....NO JOKE, IF you don't the car will run like dew dew with all those mods, MAf is your easiest solution or buy a speed density tuner and prepare for a learning curve...MAf is what you need
