26" vs 28" tire
This is where I'm sitting right now. I'm running mid 10s at 140 mph and I am starting to get whining in 1st through 3rd in my transmission. I love driving the stick but I could be in the 9s right now plus I wouldn't have to worry about tearing **** up as much. Th400 might be my next big mod I do.
Th400, and if you find the OD is absolutely needed put a gear vendor's on it. That will suck up a bunch of power but it will give you an overdrive.
I would highly suggest making this move before spending 4 grand on another transmission that has a clutch that will constantly be a problem, etc.

For mid 10's I'd do a 28 of some kind, a 2 step, and if you don't have them already, I'd investigate double adjustable shocks. All that would give you more to work with.
Th400 with a gear vendors overdrive which you can specify how much overdrive that is, or a 4L80 would be your best bet trans wise, if you have to have OD.
I'm not telling you what to do with the car or your $ but if you stay the stick route be prepared to be in a circle of endless breaking and fixing and breaking and fixing, it will never stop with a factory T56 tranny and drag racing.
If you must keep a stick shift in the car I would highly suggest looking into a real drag racing transmission... you can drive it but it's gonna eat clutches like candy since you will be using a softloc style weighted clutch for tuning reasons.
The 4l80 really sounds like it would be your best option... fwiw.

Verdad Gallardo ^ this guy speaks the truth. I have years and years of t56 frustration to prove it. I was so fed up of pulling my trans every weekend I parked my car for 3 years and didn't blink twice at it.
I'll put my 2 cents in. 550 hp n/a and 650 with a 100 shot 3300# car stock t56 best of 10.33 on motor and 9.96 on a 100 shot. single adjustable shocks up front and doubles on the back. On good track prep days 1.39 60 on bad days 1.45
I ran 28x10.5 stiff walls with the 3.90 gear
My car liked slipping the clutch slightly also may have helped save the trans.
Went to a power glide recently. Miss my 6spd

Again, FWIW- I grenaded my t56, found a guy willing to give me a complete ready to swap in th400 for the broken trans and new clutch.
By far the best decision I have made with my car. If it wasn't a turbo car and needed more gear I would have opted for an OD trans, but it's very drive-able with the 3.55s IMO

I am going to go T56 Magnum. My reasoning is I love my 6 speed and the car is not a dedicated drag car. I am not sure I would like the auto the 80% of the time it will spend on the street.
Anyone has experience with these? they are supposed to be unbreakable.

I'm here with you. I love driving the 6 speed but I would be way faster with the auto and have less headaches.

I want to drive the car with air and be able to travel long distances with it if I want to. It's super clean, not looking to make the full conversion. Not yet anyway.

Ha I g had fast street car and race car I stand by the 4l80 being a good fit for you. A manual valve body setup would make it fun to drive, and you would have your overdrive to go on all the trips ya can stand

The tire choice has me undecided still. Everyone makes a good argument for their suggestions.

I am laughing because I can see myself a few years down the road with this thing as full drag car. I will say to myself, Darn it, JL ws-6 told me so!
