I'm in the middle of converting my fox body to a 4.6, and at the point where I need to find an engine for it. A PI 4.6 out of a mustang is impossible to find around here, but there are plenty of F-150, Crown Vic, town car, and explorer 4.6's. The DOHC 4.6s are all also either way overpriced or in terrible condition. I need to know what all absolutely must be swapped off of one of these non-mustang 2v engines to the mustang version. I already know oil pan, exhaust, flywheel, and possibly intake manifold and oil filter adapter. I've seen some people say the timing cover needs to be swapped. Why would the timing cover need to be swapped?
Also, is it worth it to spend a few hundred more dollars for an aluminum block explorer/mountaineer engine?
