The T-56 is a nice piece, but its not needed. Its more of a bragging rights piece. Not only that, but it weighs a fair amount more than a 5-speed. The cost to install one into your car would be $2700 for a standard T56 rated at 440 ft/lbs or $3172 for a Viper T56 rated at 550 ft/lbs. As for can see, its extremely expensive, and yet it holds less power than a TKO600. These are new costs of course, but you'd be hard pressed to find one that would bolt to a 5.0 since the bell is integral to the tranny. All stock T-56s bolt to Vipers, LS1's or modulars.
