May 1973 MOTOR TREND Magazine reports, on page 126, that the 1973 Pantera has the following specifications:

1st: 41 mph @ 5,000 rpm
2nd: 62 mph @ 5,000 rpm
3rd: 87 mph @ 5,000 rpm
4th: 108 mph @ 5,000 rpm
5th: 131.5 mph @ 5,000 rpm

So, at 8,000 rpm:

1st: 65.6 mph
2nd: 99.2 mph
3rd: 139.2 mph
4th: 172.8 mph
5th: 209.6 mph

This is with Tire Size: H60x15, original tires in the rear. I do not know how that compares to the diameter of your rear wheel/tire size, but I'm guessing add or subtract 5-10% to the mph's for each gear. I'd have to get out the old Calculus and College Algebra books to add or subtract the radius/diameter difference and 'do the math'.
