Ford with a Mopar engine in it

The cylinder head for the 385 series engine is superior in design to the 440 Chrysler head. First, they were all true quench designs, much like the bog block Chevrolet. They all had canted "twisted" valves like the big block Chevrolet, to straighten out the air flow, similar to the Hemi. They came in both open and closed chamber designs, easily available in each, while BOTH open AND closed chambers were STILL quench designs. Also, they came for many years with adjustable rockers.

Ford's MAIN number ONE reason they were not pounding Chrysler into the GROUND was because some idiot at Ford Motor Company decided that conservative camshaft timing was better. Ford made their camshafts with retarded camshaft timing from the early 60s all the way through to the end of the 351M/400 engine in 1982. Some as much as by 6*. Yeah, somebody overdosed on their stupid pills.

All that said, I still kinda think a 440 in that truck would be pretty dang cool. Why not? Lots of engine swaps are done all the time. That would be a different one.

I like the Cummins idea, too. I've thought about a 1st generation Cummins swap in my 75 F250 2WD. There are several companies that offer kits. A Cummins and NV4500 in my truck would be really badass.

Those trucks are timeless. Whatever you put in it, as long as it's not as long as it's not gay *** and wimpy will be cool.
