Hey everyone! Haven't been around in a while, nice to be back. I'm looking at a throttle boby to install on my blazer. So far I'm looking at the TB, the intake, a wire harness and that's all ( so far). I gotta see what I can finagle the guy with. What else will I need? A computer or will the one over my glove box work? o2 sensor? knock sensor? New distributor? Oh, by the way it's an 83 blazer with an 88 350 motor. Carburated ( obviously) What is different between the throttle body and TPI. Do I need the same garbage to make it work? Or is the whole enchilada different?
