Okay i have fully ported and polished heads and a f1 cam here are the specs .591/.569 230/226 112 i had to run factory manifolds cause of the setup in my 93 truck. stock bottom end stock size valves. What size injectors should i run and what should i put the fuel pressure at? The reason i ask is we ran the truck today and it had no power turned the fuel pressure up and it has power until more than half throttle then it bogs and sputters. I have factory injectors but the fuel pressure is turned up. when the pressure was at 58 it ran shitty then we turned it up to like 70 and it ran good until more than half throttle and when it was floored it ran like a stock 305. so my problem is i have no power what is the deal. my sisters 305 camaro would kill it. thanks for any help

Stock 28.8# injectors should do fine with that setup.

What's your fuel setup look like? What pump and what size lines are you running? What regulator?

i have an aeromotive regulator. stock injectors and a 255lph inline fuel pump. stock lines. my fuel pressure stays at a consistant rate of where i set it at. just has no power
