New Aftermarket EFI System

Local pic a part here sells any ecm for $35 whether it s a 7747 or a 0411, have any salvage yards around you?

Yeah, that's the same here.. only issues are the crank/cam sensors, coils, and tuning software.

well if you use a 350 vortec bin you only need 1 coil, the ICM is called the cam sensor in those engines, vortec 350 timing cover fits 1 piece rear main seal engines maybe 2 piece also just uses 2 less bolts, its composite so it needs to be replaced anytime it is removed might even come with new crank sensor. Tunning software is a wash unless you already have it for the 7427.
