I have a 292 with a z-28 T-5 and I am running a 3:55 Posi on a 8.5" Nova 10 bolt. The tranny's first gear is a 2.98 (low) and the OD is 0.72. That gives me great low end starts and great hwy cruising. I have tall 30" tires on the back. 275-15/75 series.
I am running 65 mph and the tach reads 1850 rpms.
16 mpg in town and 20 mpg on the freeway
