What trans behind a 5.8L swap?

What trans are you guy's running with the bigger small block swap? I could go T5 or because the car is automatic I could go a C6, AOD or 4R70

Sticky tires and a stock WC T-5 = broken T-5 parts.

Stock s.o. plus t-5 equals broken motor mounts. I replaced 6 in about a year. I have been known to be hard on stuff though.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

My car makes a little over 400hp to the wheels from its supercharged 5.0 and I started off with a fresh built 3.35 T5. I race the car with 26x10.5 MT ET Street R bias tires and gotten a best 60ft of 1.61 running 12.00s at 116+

I blew that trans up after 4500 miles.  I bought the G-Force Street T5 with the 2.94 box and with a .59 overdrive.

This thing is a beast. A little louder than a stock T5 but I was able to step up to 3.90 rear gears so the car pulls like a monster in 3rd & 4th gears. Its rated to 600hp/500ftlbs and cruises 80mph at 2200.  I have $2600 invested into the trans and the new clutch disc to complete the swap.  I really couldnt find a better option at that price level and without changing 50 other parts on the car.

deathbypsi. Good to know. For now the car will just be cruising around with a basic stock 5.8L with a 5.0L HO cam in it running Fitech Go EFI. Was looking at keeping it auto with a AODE or V6 4R70W and a trans controller. I am looking at the cost between swapping to manual or keeping it auto.
