Companies aside, I have to go with Brent's advise on the trans. A TKO is a much better fit than a T56 in this application. I cant see any reason to run a T56 in any Cobra, let alone this one that is over cammed and tall(er) geared. At the high speeds where the gear split advantage of the T56 would be useful, a Cobra has crashed into the aerodynamic wall.
The higher weight, physically bigger in every respect T56, offers little (if any) advantage and does it at a higher cost.
Don't get me wrong, the T56 is a cool trans, just not in this application.
The TKO is smaller, lighter and cheaper just a better fit in my opinion.
