T56 Magnum. The close ratio has the spread I want and will work well with the Double OD and a 3.90 rear axle here in Texas where the 70mph speed limit is common even in town and there is an 80mph speed limit on a few highways I frequent. I have owned several 68-70 Mopar muscle cars with the A-833 with the 2.66 first gear. The 1-4 ratios are almost the same as my beloved old A-833. Anything much lower ratio than that with a big block in my 3200lb car would be too short.
The transmission can handle my 600hp 440ci engine which has a 7500rpm redline. The synchros are supposed to be a step up in the T56 Magnum. I have driven 2 cars with OEM TR6060 transmissions, I like the way they shift.
The TKO 500 is not rated to handle my engine. The TKO 600 is close.
VSS output for my EFI controller is a definite plus and the mechanical speedo drive turns my "stock" refurbished 150mph speedo.
I was going to have to cut one way or another to fit it in, the size difference didn't play in at all. Bonus is that the shifter location was close enough I was able to use the factory 4 speed top plate on the factory console by relocating the console rearward about an inch or so. Looks almost like a factory 4 speed.
