hi im looking to swap a 4.6 into my f150. it has a ford 4.9 i6 in it right now, ive heard the 91 and 92 4.6s have sbf bellhousing patterns so it should bolt right up. are there any drawbacks to using a 91/92 motor? and would i be able to use a wiring harness from a newer car like a 08 crown vic? they are plentiful where i live and i can get a harness and computer cheap. i would assume it would work, if it will work is it plug and play or will i have to change some connectors or whatever, would i need anything else to make it run?
