I have a SPF with a 392 Ford crate engine and a Tremec 5sp, .68 5th & 3.73 rear. Not the best setup for street or track. Go with the Tremec II road race(the powers to be say that you don't need a TKO in a cobra). It has the harden gear set with the .83 5th. Then go with the 3.08 rear end. You get the same rpm=mph in 5th. But you stretch out 1 thru 4. Makes for a very nice close ratio tranny that will stay up to street and track work.

I'm with Jack21. I'm going to swap out the GT-40 heads for the AFR 185s, and Speed Demon carb. They say 75hp gain. Even a 50hp gain would worth the swap.
