Hey thanks for that information. I actually have more specific questions like; is it possible to run tbi and keep my nice new big cap hei distributor. I am doing a v8 swap on a 97 s10 but I want to use a better intake so I think I use a carbed one for vortec heads and adapt the tbi to it. I just want to control the fuel for now.

There are a couple of ways to keep your big cap distributor, but it's probably not worth the trouble (I'm assuming that it's a vacuum/mechanical advance version). The first way is to go with a fuel only setup, but you'd be giving up about half the reason to go with an EFI system. The other way would be to lock out your advance and modify it for use with a 7 or 8 pin ignition module. It'd probably be easiest to go with a big or small cap distributor that already has the correct module and no advance mechanisms. There are plenty of reasonably priced distributors out there.

That said, I have driven a few fuel only vehicles that performed well. I do prefer to have timing control, though.
