i just got finished installing a p90a head on my 79. it runs gret and very quiet until i slam the pedal to the floor. it stutters and then gradually gets going. when i ease on the gas it runs great throught the rpm's. but, when i mash the gas it just put puts. whats wrong? is this the fuel pump? any other parts on the engine that could be causing this? i got the plugs gapped and got brand new taylor wires. im pulling my hair out here guys. later

Re: injectors?

not the fuel pump. check the tps, it may be out of adjustment. timing could be suspect, along with vacuum leaks, ect... break out the fsm and go through the troubleshooting chart in the engine fuel section.
