engine swap
 

ok got another question...my mechanic seems to think i may have a problem with the wire harness in my 86 ls but the guys at gm tell me there should be no problems if i throw in a 350

most GM small blocks have the same needs as far as electrical. If you are carburated there should be no differences between the harness's. I haven't done a carburated swap in about three years but if i remember right there should be 3 or 4 wires on the starter, 1 bolted to the alternator (and two in the plug),1 to the dist.(2 if equipped with a tach), and if you have a electric choke on the carb there will be one there. this is with using mechanical gauges, if using stock oil/temp sending units just swap them to the new engine and the motor should start. (this is not including any emissions equipment, I am not required to have my vehicles tested)

It may depend if you now have a V6 or a V8 engine in the Monte. I have an '86 V6 which has a fuel injection harness. I am converting to a 350 V8, non-computer carb, non-computer distributer, and SS gage package for the dashboard. Also changing out the 3 speed, lock-up transmission for a 4 speed overdrive (200R4). I will have some re-wiring to do for all this.
