I'm not sure about just the TBI stuff but, when all was said and done, I got mine for just under $1000 with *EVERYTHING*. Alternator, AC compressor, PS pump, mounts, complete wiring harness (cap, engine, under dash), ECM, TBI, and a shiney new 350 crate motor (still had the tags). That price also included some other stuff like the engine oil cooler and lines, starter, and various odd pieces I saw lying around that I needed.
I even got to see it run (purred like a kitten) before it was pulled from an 89 Suburban. Hehe, I don't have a lift anymore (or place to put one) so I hauled the K30 (minus front cap) down to the yard on my trailer and had them set it in place instead of renting one. Still got a few things to finish before it moves on its own though. Fuel line work (man, wish I had gotten the frame hard lines), gas tank exchange (see other post) and figure out how to get hoses from the 350 to my diesel (wide format) 4 row radiator. Oh, and I gotta mate the diesel duel exhaust to the exhaust stubs I got with the engine. If that thing had a VSS, I missed it.
