Mainly a street car?

Stick with the 5 speed. The fun factor is off the chart and you keep the overdrive.

I have been looking at the Ford Racing Tremec M-7003-R58H from the old 95 Cobra R set up. It has been upgraded and can handle 600ft lb of torque like a TKO 600. It is a close ratio in the first 4 and has a.68 OD.

Track car?

Go with the auto.
