But then I'd have to change the gears in the 8.5" rear end and lose my low end launch... I want my cake and to eat it LOL
What rear gears you running? I'm obviously running the cammed 5.3, 4L80 with 3400 converter and 3:73's. I cruise at 70 around 2,400rpm
3.42 Scott, but of course no overdrive with the Muncie. Really looking forward to having one, or two though 🤣
Cake and eat it too - yup, I understand. That’s what you ought to have.
Id look hard at the rebuilt, guaranteed unit or a known, correctly functioning unit.
Supposed to go look at one after work tonight that popped up on Marketplace. I found it within 15 minutes of being posted and was the first to respond. Fingers crossed. It's also only 15 minutes from my work. Wish me luck
It seems to me trying to get a t56 swapped in a gbody for cheap is futile. Most people who have a t56 want 2k or more for a beat on stock trans. They point to the price of a t56 magnum, even though they aren't the same. I figured 3-4k for a t56 from an fbody. 5-6k for a magnum. I'm sure it can be done cheaper but not by much. I've been saving for the magnum. If I get done with the car before I've got the funds, I'll put an auto in it. That is highly unlikely for me.

As nice as your car is, I assume you plan on keeping it, plus you can still drive it. I'd think the magnum is the way to go.
The Differences Between the TREMEC T-56 and Magnum 6-Speed | TREMEC Blog: Get Connected
An in-depth look at the similarities and differences between the TREMEC Magnum and T-56 6-speed Transmissions

With the 25.5" & 3.42 combo, the 4spds 1.00 final drive yields approx 2700rpm @ 60mph.
The t56 4th gear yields 1800rpm @ 40mph. Great for inner city traffic getting to the highway.
The t56 5th yields 2160rpm @ 60. Great for merging onto the highway & local highway areas.
The t56 6th yields 2130rpm @ 75. Great for increased speeds during extended interstate highway driving.
Seems it's a pretty solid choice.

Sometimes even a blind squirrel gets a nut. Yay! Out of a 2002 Trans Am with 79k miles.
I fired the parts cannon last night and burnt up the remaining cash I saved. But I've got a bunch of parts coming in for the car 🙂
