Magnum and Wiring Swap

I will say that this motor pulls much better than the 1988 roller cam 318 with 915 heads that was in it. Might just be my own justification. I think going from a poorly tuned Holley 600 to efi is where the biggest difference is being made, plus higher compression, better flowing heads, and a mild cam.

I went from a 318 TBI to a 5.9 SMPI and for me the bottom end torque difference was night and day better. Even pulls a steeper hill in OD without kicking down now. Completely different rig.
