So taking my sweet time, getting around to mocking up the throttle body on my Olds FI intake. It's a BBC throttle body, I'm planning to build the motor up enough to get some use out of it's larger bores. Running into fuel rail clearance issues, on both sides actually. Think I can work around the throttle cable issue, but if I could get a smaller IAC, or an adapter that moved it vertical, it would allow some options in intake to TB adapter thickness. The LS-series IAC's look the same as the TBI ones. Anyone familiar with an IAC that is shorter but compatible? Will be running a 1227727 if it matters. I'm not even sure a 90* adapter would solve the issue. May have to live with the 2" spacer, but that creates problems of it's own. Due to intake design, not going to allow me to offset the throttle body to gain clearance either.
