Notice it's a little smaller than the Hughes grind in the article, and which targets out of the corner torque in auto crossing. The 3.25 gears (Ford nine inch?) you had mentioned will make the combination more favorable with a conservative cam. That '75 Valiant is no lightweight in itself until you remove the crash impact absorbers from the bumpers.
