36lb injectors to big for a 5.3? This is the engine I have.
2004 5.3L Vortec, nitrite coated crank, forged pistons/rods, 2.00/1.59 SS valves with stock heads, 10:1 compression, Comp cams 227/235 .614/.621 cam, LS6 intake, and ported throttle body. It is about 420hp at the crank.
I am still using stock 28lb (31lb at 58 psi) injectors and the duty cycles I am seeing are a bit high. I'm thinking of getting Fast 36lb (41lb at 58psi) injectors.
What do you experts think?
