Today Cosmo and Alec stopped by to hang out. We installed some 8R19.5 tires and wheels on the rear axle, approximately 2" taller than the original tires (Good for about 150-200 rpm drop)
Then we all crammed in for a test drive. Found a suitable straight spot in the road and got it up to a GPS verified 63 MPH on the way out and 70! on the way back.

It runs nice at 50-55 and I suspect with some better engine tuning it'd be happy at 55-60 for continued running.
