S-10 V-8 Conversion

I have 1994 S-10 4 door blazer with a 4.3, and I plan on putting a Chev 350 in it. Is there a way I can change the wiring so that I can use the throttle body fuel injection instead of the cross fire fuel injection?

I doing a V8 swap on mine but going carbed. I don't think the harness is the same form the CPI to the TBI. It would be best to use the stock harness form the V8 I think.

your best bet is to find a tpi injection system in the junk yard from an older 350 camero or firebird and grab the intake manifold and wiring harness and ecm.

Go with the later tpi off a vette that use's the speed density instead of the mass air flow. Alot easier to route the ducting. But if your needing to keep the same year of motor as the blazer the try to find a wrecked fullsize and use it.
