Toyota: W56 vs A340

Toyota's W56 manual has a 0.850:1 OD, while their A340 automatic has a 0.705:1 OD.
Is the better gearing of the automatic enough to offset the internal hydraulic pumping?
I'm trying to plan my next build. Plans include a dual-fuel Toyota 22R for propane over a DualJet, a 2.412:1 axle, a single-seat chassis with exposed suspension for less drag than an actual car, and goals of 70+ MPG with 1g cornering. Tires not chosen yet, still trying to source wheels.
Will be a leaf-sprung solid axle hung over the lower frame rails I'm still designing in a 3d computer modeling program. The axle and gears are already on hand.
