My dad had a really nice '76 F250 that had a 390 and a C6 in it. That truck was an animal, stock for stock it would have easily out pulled my old '85 that had a 460 in it. Drove a clapped out '75 high boy around on the ranch when I was a teenager, it had a 360 that ran super strong... my buddy had a '69 F100 that he built a 352 for, also a very strong running truck. Never had the muscle car experience but I like FE's in pickups.
460 guys all seem to have the attitude of "ya gotta do this, and that, and get D0VE heads, and headers, and a timing set, and a cam, and a big carb, and ..............." and THEN you've got a good engine... after all that work. Stock form after the late 70's were just smog choked turds.
