Both are strong enough.
Muncie - Cheaper???, easy bolt it, no overdrive. About a 6 on the WOW factor.
T-56 - Costs more???, more "engineering" to bolt in (espically for a clutch fork), 2 overdrives. About a 9 on the WOW factor.
If you have <3.08 in the rear, Muncie will be fine.
If you have >3.73 in the rear, you'll like the overdrive.

Muncie's will hold up better, cause they were strapped to factory torque monsters
