@Mastermind 360 hp peaked around 1970, after that got worse and worse until it phazed out, 390 phazed out early so never got the bad rap that the 360 did. With a bit of work a newer 360 can be made to run as good or even better than it's older counterpart. As originally designed were an excellent purpose built light truck engine that performed marvelously until the smog era came. If a 390 crankshaft could be found, you could literally make a 390 out of your 360. These aren't laying around any more like they used to. Nor are the 428's taken out of smashed Mustangs, was a good trick while it lasted.
If gas mileage is your greatest concern, cut off Bubba's nuts and buy him a Prius. I think given the choice, he will take the truck.
Not to worry, no one with a new truck will hook up to the back of a 360 powered Ford anyways, and if they do they are in for an education in physics.
