The tranny is a TKO 26 spline wide ratio. Rear gears are posi 3.31. I know I want to use a hydraulic throw out bearing...and have not decided on clutch make/type(single or dual disc).

Congratulations on your acquisition. Fun is in your future.

I've not been on the forum lately as I'm spending all my spare time driving. Normally we drive to commute, or to get somewhere and it's just a part of daily life and often a chore.

But driving a Cobra is driving you want to do. And I've been doing just that. I put on 1200 miles of smiles. So glad to be at this point.

Enjoy yours too.

Arthur, congratulations on getting your car up and running.

The commonly accepted ratio for driving to working on the car is ten to one I believe, so you have plenty of driving to do to balance the equation.

Hoping you chalk up lots and lots of miles in the lovely fall months.

I'm trending for completion in about 4 months. Just in time for winter! So Cal winters arn't that bad. My engine builder is in the middle of making a change I've requested...he originally built the motor with Sportsman N351 heads, makes lots of power but are iron heads...I'm changing to aluminum heads to save on weight. He also mentioned my 11:1 CR will be more manageable in avoiding detonation because the aluminum heads dissipate heat better than iron. I'm hoping it dyno's as well as the other heads!

Thank you Don, The car has been my daily driver. And I make sure I drive to lunch everyday too. 1,200 miles/1900km.

Still learning the Holley Commander 950 Pro Fuel injection program and getting a better understanding. I love the fact that it is so tunable, fuel & ignition. A lot more to learn, but having fun now for the most part.

So I have the dyno results from my head change. It's not a direct comparison because I wimped and backed off on the cam and compression a little. I need to be able to enjoy it on the street as well as track! HP came in at 592, but not until after changing up the carb. I started pulls with the same quick fuel 850 as I had before, but dyne readings were clear that more air flow was needed. I found a Holley HP Ultra 950 locally(I was on the dyno and time was ticking!), bought it and mounted for test...went from 550 to 592 out of the box! There's probably more there after some jetting but the curves looked fantastic so I let it be. Need to move on to next step!
