IAC options?

You have any pictures of that? Like this? http://www.ebay.com/itm/Vortec-96-20...ht_1004wt_1399

I want to keep the stock air cleaner, so the BBC TB obviously helps in that goal, but adapting the air cleaner to a different TB might be easier than trying to force the BBC TB to fit. Apparently that won't work though, I'll have to measure, but the intake I'm working with is cast very goofy, there isn't much metal to work with, the 454 bores are almost too large to fit. Hard to tell from this image, but its kind of like a cylinder in an engine block...too much boring and you end up hitting "air". http://www.gmcmhphotos.com/photos/40...ion/p3687.html It's the nearest intake, you can just barely see the passages cast in it. Unlike the TBI intakes of later years, the passages for vacuum are cast into the mounting flange of the intake, vs being all in the TB.

So far it appears TPS is no issue, it's just the IAC and throttle cable stud. If using the BBC TB, think I can just re-do the throttle cable stud so it's inboard of the plate it mounts to.
