Chevy's in the wild

I think the coolest part of the 632 package is it's controlled by Holley from GM
I've wanted to get a copy of that tune, because back in 2017 I built my own 632 and I control it with a Holley. My cam is very similar, and my injectors are even darn near the same thing. I've often wondered how close my tune is to that one. The GM uses Terminator X and mine uses Dominator EFI, but I use both software so it would be easier to compare just for fun.

Now, that ZZ632 wouldn't work for me, because its so tall it wouldn't fit under my hood, I have conventional 24deg BBC heads and SV2 intake. I actually have a large 16"OD x 4" tall element on it, not a choke. Even then I keep it clean so it won't restrict the engine.

That would be neat to get a copy of it, for some reason I didn’t think it came with a tune but if you spend that much on one it better.

I was under the impression it comes with the Holley Terminator X ready to roll. Its a 58X sequential MPFI BBC system with 8 coils on top the valley cover under the intake manifold.

That one is likely more HP than mine since I don't have raised symmetrical port heads with titanium valves, so the top end is likely a little more, mine is probably around 900 HP I would guess.
