Fuel injection system

I'm changing my 94 S10 blazer from a 4.3 to a V8, I like the simplicity of a throttle body fuel injection, when I change over can I keep a throttle body fuel injection or do I need to change to another type?

Just get a v8 with the injection system still on it. I understand that the fuel pumps are a little different, and you might need some wiring from the doner car... or talk to painless wiring for an adapter

try and find an older camero, firebird, or vette with tpi injection for a 350. i know the late 80's model iroc camero's had a optional tpi 350 that ripped. see if you can find that motor. a vette motor would be nice too.
