I'm a Chevy guy, not sorry! I agreed to rebuild the motor for my friends 1983 mustang 3.8 v6. The car belonged to someone who shouldn't be allowed to check the oil previously... I had to rewire from scratch. I had replaced everything and got the car running. Due to the wiring issues I ignored the oil pressure gauge figuring I messed up the wiring, turns out the oil pump I replaced was bad and the engine seized up during fine tuning everything. Machine shops in my area have doubled (or more)...
