    25326903 injectors for a 98 Vortec

    They flow around 33lb/hr at 58psi. Would that be to much for a mostly stock 98 Vortec motor.

    Only mods i have done is headers, 1.6 rockers and running a marine intake. May do a little cam down the road.

    Get your data correct and these will do fine. Im running factory 6.0 injectors from an 02 Denali. Flow rates are 25.2 at 58psi in my tune i believe. My 5.7 vortec truck has long tube's & full 3" Y into a 3" single in single out muffler and the Victor Jr 29135 intake. these are bumping 65% duty cycle around 5600 rpm 12.5-12.8 afr. With 33lb\hr you will definitely have some comfort space for a cam swap. Finally getting ready to fire up the build in your sig? I remember you had said in my thread a few month ago, she would be put together in a few month's time.
