I want to know will a 2003 crown Vic motor 4.6 will fit my marauder?
Why would you want to go to a single overhead cam engine. The DOHC 4.6 in the Marauder is a great engine often going in excess of 250,000 miles. Swapping the engine to a SOHC maybe complicated by computer programming and engine wiring differences. Perhaps join the marauder forum and post this question there.
