Sorry in advance for being a little naive on the ECM/ECU driven motors.
I have a 4.3l 262 throttle body injected v6 from a '97 SS s-10.
But I don't have the computer to control injection/emissions etc.
What are my options since I don't have the computer to control this engine?
To use the engine without the computer I could just replace the intake manifold and carburate the engine, right?
But I think I've heard that the TBI controlled engine puts out more horsepower and is more reliable.
So if I want to stick with throttle body injection, what are my options, and which ECM/ECU's could I use?
Thanks in advance.

To keep the tbi you would also need the wiring harness for the engine and computer.I would find a vehicle at the salvage yard that has the same equipment as your engine.From that vehicle you would pull the ECM and wiring harness.
You would then be faced with the daunting task of wiring this into your vehicle.Can be done with alot of patience.

The easiest route is to switch to a carburetor and standard HEI ignition.Here is a thread about that.

Hope this helps.

Thanks,
Which would you prefer on a performance basis?
TBI or carb?

I don't think there is a carb intake for the Vortec heads other than the cast iron q-jet marine intake. I was looking for a TBI intake for the Vortec heads so we could put a '00 vortec 4.3 in my moms '92 Sonoma and that marine intake was all i could find that would fit those heads. The only solution i could come up with was take the marine intake and put a TBI to carb adapter on it.

That was a few months ago so somebody might have came out with something else since then.
