i have a 84 F-150 that has the 351 and c-6 tranny what is the biggest problems ill have putting it in a 1980 mustang it has already been witch from a 4 bagger to a V-8 .Any help would be great thnks

you will need motor mounts for a 5.0 to 5.8 swap you can find them form places like 50 resto and mustangs unlimited.com. Also you will need a fox body dual sump oil pan and timing cover. Which i think you can get form jegs. Hope this will help you out

like stated above you need the dual sump oil pan and either the lower motor mounts or a slightly raised cowl hood.
