1986 police engine

I believe (don't quote me for sure) the oil came from the oil sending unit, through the cooler, and back through the fuel pump bolt.
That's correct. I had one years ago when I didn't realize how many good parts were there to save. I bought the car with a bad trans for $100 to get the 360 heads and intake and scrapped the rest of the car. The exhaust on mine had a precat on both sides of the y-pipe and then another larger cat after the y. I'd sure like to have it back now.
