Very much agreed. As I’ve said before, my Pantera has a .655 5th and the GT40 has a .642.

I love them both.

Screaming tire smoking 1st and 2nd. Nice lazy 5th.

Every time I see a car with a 3.77 ring and pinion, they’re always slipping the clutch to take off.
GT40 or Pantera…

Me likee tall 5th gears. After all, 4th and 5th are too close together in my opinion anyway….

FWIW,
Kirby
