Holley has a lot of options for A body swaps, I was shocked that they had options (engine mounts, transmission mounts, and oil pans for my 71 POWERWAGON, I went with Holley terminator x with for my truck Gen III hemi. Pricey but easy installations and user friendly. My truck has space for days...

Yes sir!

It will need a fine tune. It does learn on its own. You gotta set parameters on when it starts to learn. I’m having a hard time fine tuning cold starts. But other than that truck runs great. Holley sets these ECU’s to run a little in the rich side. Dialing it in professionally or taking the time...

It was a breeze to be honest, instructions made it dummy proof. Effective grounding of the ecu is crucial. Every harness end was labeled to ensure proper connection. Uploading software and firmware was the only tricky part, but having a basic understanding of their terminology and their function...

Hey guys did a 5.7 hemi swap. Truck runs great, just looking to do some tuning to get to run right. Running a Holley Terminator X, any one in the California Bay area?

Gotcha, this is a stock 5.7 hemi in my POWERWAGON with terminator X. I did keep the MDS and VVT, yes I’m using my stock AF metering numbers.

Yeah, that’s what I’m worried about. Doesn’t quiet sound right. Asking around and trying to do research.

Setting up timing on my Holley terminator x, ignition timing is set at 15°, timing at idle is 12°, timing at cruise is 35.3°, and ignition at WOT is 12.0°. Stock fuel injectors, does this sound about right?

Yes, I corrected it. Since I’m using a GM throttle body. Re-wiring was necessary. Had to swap two IAC coils leads, from a Chrysler to GM configuration. Then crank position sensor had no feedback, changed that out and immediate start. Had to adjust IAC, seeing 0-1 now.

Good morning guys, did a Gen III hemi swap on my POWERWAGON, ‘13 5.7 Hemi. Went with a 92mm Holley sniper cable throttle body and Holley sniper fabricated intake manifold. After setting software and firmware, went through the GCF wizard for a base calibration. Engine fired up after few cranks...
