mounts are the same between a 302 and a 351w/c if you went up to a 360 or larger, you woulda had to put adapters on your frame to make the mounts work, the tranny might be a problem fitting up to a newer ford block, but i haven't messed with a tranny connecting to the 351, i used to have one of those 5.8s in my 87 mustang though, tough engine, til i drifted a corner too hard and ripped the bead off and totalled the car
