Most yards around here are DIY. I don't go so much anymore because there are individuals that go through and pull most of the good parts for resale. Regardless....
I picked up a complete GM TBI setup from a 454 pickup complete with harness, computer, throttle body with injectors and computer for $150. For my beater truck it's a worthwhile endeavor to tinker around with. I have another one in reserve for the family Grand Wagoneer, but I want to wait until Kermit the beater truck is up and running so I can play with different combos and tunes.
The jist of this being, that for what basically boils down to a play toy or whatnot, it can't hurt to try these type of upgrades. Sure, a carb may be good on the daily mill and way better on a hot engine, but why not try for a little more drivability or ease of start up? The worst that can happen is you are putting the carb back on next Saturday.
I do actually have a little experience with EFI engines.....
