I just finished up my rebuild of my 5.0 It's a bored to a 306, TFS Stage 1 cam, TW Heads, 1.6 rr, Edelbrock RPM Intake, BBK headers, 75mm Mass Air, 30lb injectors, 255LPH fuel pump, and 70 mm TB. Sounds like a beast but I am having some problems with it idling. Could it be my IAC? What else could it be. Timing is set at 32 degrees. Cam timing is at 0 degrees, I just line up the dots. Any help? =)

Timing with spout out should be 10-12*... check the fuel pressure...30 lbs with that fuel pump on a 306 is a little big. Set the FP to 38-40 (no vac). Set TPS to .97-.99 volts.

Those 30 lb. injectors are overkill. Is the MAF calibrated for 30 lb. injectors?

Yes the mass air is calibrated for the 30lb injectors. the reason why I went with the 30lb instead of the 24 is because I will eventually be shooting 150shot of NOS. Trickflow says that the timing should be set at 32-34 degrees.??? or am I wrong?
