I'm going to guess the 478 that was used in heavy duty 1960's GMCs.

Probably. In modern times, I'd say Ford's 4.0L.

I think WMJ has it, tho GMC also had a 305 CI V-6 (5.0L) in the '60s.

I think Ford has a 4.2L in the Freestar don't they?

It's not, but the F-Series uses it. GM has a 4.3L V6 in trucks.

Cool question. Those 7.8 liter V6s are insane.

High torque, low rpm operating engines. International has some Ginormous ones too.
