Well I 've towed over the rockies lots and my 92 318 Magnum had more nuts than my mid 70's big blocks that I towed with. All stock trucks, all bought new and in good condition.
This 76 440 truck got about 5 MPG on a trip through the mountains just towing a single axle U-haul, not even a car trailer and it was sweating heavy doing it.

Well lets do apples to apples. Not a EFI later model to a 70's low compression carbed motor.
Try a 92 454 Chevy to your 92 318 and see how it goes.
Or a 75 440 to a 75 318.
This thread is about early 70's trucks so why are you throwing in your 92 and then late model diesel?
