2.8/3.1L AC and Smog Delete
[backstory]
I'm running a 60ºV6 in an Isuzu Trooper - originally had a 2.8L TBI, I have a 3.4L now which I ran with the Camaro SFI system, but there were some problems with the way it fit so I eventually reverted back to TBI on the 3.4L.
I converted to MegaSquirt with TBI to get familiar with the platform for another project. Well, an injector failed and over-currented my MS2 board which lit it on fire. Ooops.
I'm taking this opportunity to go back to MPFI (can't go to SFI because I swapped cams, no sensor lobe). I'll probably stick with a tunable GM ECU this time, probably a '7727/7730.

I'm going to be using 2.8/3.1L intake and brackets on my 3.4L because they will fit much better in the cramped engine bay of my Trooper. However, I do not have a smog pump and my AC has been inoperable so long that I have removed the compressor. No problem with the Trooper because there were models that did not have A/C or Smog. I don't know if that's the case with the Camaro setup.
I've been google image searching to get some ideas about the belt routing, and came across this thread: https://www.thirdgen.org/forums/v6/5...00-t-88-a.html
Looks like A/C can be omitted easily, barely clears the water pump, but there may be an idler in place of the smog pump which I can't see.
To avoid reinventing the wheel, I'll ask. Is there a recipe for A/C and smog delete? Measurements, part numbers, belt size? I'm sure I can figure something out, but if you guys have some input, I'd love to hear it.
