At 70 I'm at 2850 rpm. So yeah, taller gearing with the torque converter locked.
Larger/Wider Tires though.
Obviously taller ride height.
And the wagon shape itself leaving that huge gap in the wake.
I'll be working on it a bit more after haloween. Along with the A B A B tests.
Also worth mentioning, I have overload coils in the rear. These are great to fix the problem of the back of the car sagging when I have it loaded down with oak, but in normal use actually gives the car a slight rake, I think this is also hurting mileage somewhat.
