I think you can find what you want at summit racing, Jegs and many other performance parts catalogs/ stores. Edelbrock and holley make stand alone tbi's to meet pretty much any horsepower need, but keep in mind you need to address the fuel pump and lines as well

I was on my way out the door when I sent this to you, I want to elaborate on the fuel pump and lines part. When you add injection even TBI, it will probably require more psi than the factory fuel pump will supply. That means you'll probably need an electric in line pump. I am sure what ever you choose will have information telling you what you're going to need to have. I just wanted to make sure I mentioned that, odds are it won't be just plug an play. You'll end up at the very least re-routing your fuel line to an electric pump and doing some wiring to get it running. I suggest using one of the IGN terminals in the fuse block as it is off untill you turn the key to start the car. Preventing the pump from running constantly and draining your battery or causing other problems

i would buy a manifold and all from a junkyard for just about any chevy 350 (not lt1, not ls1, and not vortec) i got mine injectors and all for about $85 i got the computer and sensors thrown in for another $100, and a harness from "painless", and it was pretty easy. all for about $700 the most expensive part was the fuel pump. i have a tuned port injection manifold, but i got a sequential injection computer because the injectors have the same plugs and the computer has no idea what manifold you're running

Robb's also correct also, the main difference is how much work you want to do. obviously new parts will come with directions, tech support and a warranty, but there's more cost involved. It just depends on your budget and experience, for myself I would lean toward the new parts only because there are directions and tech support. My experience with fuel injection is limited and getting used parts you could end up replacing injectors, or even the computer if it turned out to be bad, and then you end up no further ahead cost wise.
