First, tell us about the engine you are building.

well im taking my 4.6 and stroking it to a 5.1(Lunati forged crank, 4380 H Beam rods, CP pistons with a 17cc dish) PI heads with a stage II port and polish job. xtreme energy comp cams (intake 274, exhaust 274)  PI intake, stock throttle body, 255 BBk fuel pump.

any boost? if not then I would stick with 42lb but if boost then I would get 60lb injectors. I ave 42 on mine just with a blower and nothing else modded.

see i was thinking like 38 or 40lb injectors just as a guess cause my cousin has a 94 mustang with just a vortec v2 and he has 32 lbs and his are maxed out on 8lbs of boost.   sorry for the late reply i havent been gettin on here lately but thanks for the info bud
