Look into the Tremec TKO 600 or TKO 600 (road race) 5-Speed tranny and go with 3.73 rear gears. New TKO can handle 600 ft/lb torque which is nice.

TKO 600 5th gear = .64

TKO 600 (road race) 5th gear = .82

If you do not race and want to cruse, go with TKO 600. If you race or want higher RPM/noise go with TKO 600 (road race).

Big plus for the TKO 600's is that it has 8 different shifter locations, based on where you want it the shifter can pop up about most good locations for your Cobra

Good luck.
