Gears are great for that pushed back in your seat feeling. Almost any car benefits from lower gears, even those that don't make much power feel like they have balls when they are properly geared. Fuel economy suffers, but we don't really buy muscle cars for economy now do we?
95' GT. GT40X heads. XE264HR with 1.7RR. AODE built to 98+ 4R70W specs and PI 3500 stall. 4.10 gears. Bama tune. I got the heads for free and I still have buyers remorse.
