I put a 95 LT1 in my 34 ford. I used the stock wireing and removed the wires I didn't need. Get a GM shop manual for wireing information use the mass air flow sensor and you will not need to reprogram. I did get a hyper tech programer to correct my speedometer. If you run the same gear ratio and tire size as the doner you don't need to do this.This is OBD 1 so you can loose the converters
