Hi, Roger; I posted a message, earlier today, copping to mis-reading Hot Rod's (5/56) evaluation of the manual trannie, where HR posited that the standard MANUAL HD trannie's gears could use better ratios (which were the ones I posted. HR & the factory info agree on the PF ratios you mention. There are some slight differences in the o.a. height of 14" & 15" tires, depennding upon the subject aspect ratios. Overall, however, 28" diameters are acceptable sizes for computer-performance evaluations. How much faster your car cruises down the highway depends upon your car's physical/mechanical condition, your own physical/mental capacities, prevailing weather conditions, and Johnny Lawman's presence, in the vicinity.....
