Yeah, if you drive around in 1st gear.

Come on, no one uses a 2.50:1 rearend ratio in a Cobra....or any other vehicle for that matter.

A 2.87:1 1st from a TKO with a 3.31 gear would still be an overall ratio of 9.5. He's way down there at 8.2.

With a 1:1 5th gear, he's at 2000 rpm at 60, 1800 at 55. If that's what he settles with, then a mild camshaft will be in order.
