A Subaru Senior master tech by day and an old school Chevy guy the rest of the time, I'm new to the LSX stuff but learning quickly. I'm swapping a 2004 5.3 truck engine and a 4L60E into my 1965 C10 frame off project of 7 years now. My pcm is out for reflash and I'm almost done reworking my harness, I will be setting the engine/trans in the frame soon, I have a choice of two intakes first is stock LM7 with 2 fuel lines, 3 bolt throttle body, second is supposed to be 2004 5.3 from a express van, 4 bolt throttle body and it looks a lot like a TBSS intake and has a single fuel line system, I will be using a Vortex T rex inline fuel pump, I would like to run the single line fuel system if possible because my fuel tank only has one line on the sender and not much room for another to be added. Another problem using the 4 bolt throttle body is the wiring is different, 4 bolt has 6 pins, 3 bolt has 8, any input is much appreciated.
