ok. So I've got two 89 Chevy's, a Blazer and a 3/4t Burb. Both are TBI'd. The Burb is leaking and probably about to lose a head gasket. My plan was to just swap the motor from the Blazer into the Burb, since the Blazer is getting a 454 this summer. HOWEVER the 3/4t Burb has no O2 sensor, and I cant' find a stub on the harness for it. I need to do the swap QUICK so no dicking aroudn looking for new exhaust studs and all that when they break off LOL Question: will the no O2 motor run w/the computer from teh Burb? Will the O2 motor run in the Burb with no harness for the sensor? OR should I just say the hell with it, pull the heads and hope for the best?
