1979 F-150, when I hit 38 mph, there is a hum/howling noise from the middle or rear end of the truck. Gets louder as I increase speed. It stops completely when I let off the accelerator or shift into neutral.

Have you checked the rear differential fluid? Make sure it is full and clean. Also, check for play at the pinion bearing and check u-joints.

Let me know what you find.

fluids are all okay. Just did the initial start-up after the engine swap. Tranny was great when it was parked last Friday, before we tore into the engine.
