Yes,
A fastback with 4.10 gears, and GoodYear E-60 x 14's.
I would imagine adjusted tire pressure, meant 20 lbs. or so.

General Info; Tread width of E60 x 14 = 7.50" (26.10" tall)
General Info; Tread width of E70 x 14 = 6.25" (25.92" tall)

Imagine the possibility, of that 440 with Super/Stock rear springs, and
an adjustable pinion snubber, and 50/50 rear shocks.
A 'Drag Traction Package' with the E-60 x 14's.
Maybe low 13,00's

X-Tech,
I can think of many possibilities with that car. But your right on, with
the 440 6-barrel and fiberglass lift-off hood with a cold air package
Other smart things would have been, a trunk-mounted battery, aluminum intake manifold and aluminum water -pump housing.
With the battery, you move 30 lbs. of weight off the nose, and put it over the right rear tire. An aluminum intake good for another 25 lbs or so, and the water pump-housing another 15 lbs.
Fiberglass hood, minus the hinge-hardware, probably 50 lbs.
A cold-air package utilizing the small (back of hood positioned) faux-vent scoops. Whether the car had a Tri-carb 6-Pack package, or aluminum DP 4-barrel. it would be some monster.
Only thing that needed tweaking, would have been the exhaust system. A 3-piece cast iron unit for the drivers side would have been a possibility.
