A guy on a local board has a 4.6 from a 96 or 98 police crown vic. It has 46,000 on the clock and comes with wiring harness, ecu, exhaust manifolds, everything. He is down to $50 and I have to pick it up. My question is, what are the differences between the police crown vic motors and the standard 4.6's in that era? I know my 98 GT had the 4.6 but was non pi heads. Would this have pi heads if it came out of a police vic? For $50 I thought about getting it just to have a spare to build up over the next couple of years and then just do a swap.
