Adapt 6 speed tremec on a 454 C3?
I would like to adapt a 6 speed gearbox instead of my TH400 on my 454 corvette 74.
I've already adapted a manual transmission on a corvette C3 with auto trans. So i know the different things i have to adapt. In france, we don't have any GM T56 6 speed from F-body. I've found a 6 speed T56 which comes from a mustang gt 2002 4.6l. I don't know if i can buy this part and adapt on my 454 corvette. I have to change a lot of things : Bellhousing is sure, .......... but other parts???? Here is a picture of the part i would like to buy : http://img255.imageshack.us/img255/8176/t56zp1.jpg |

While I understand the idea behind using the T-56, it is my understanding that it will not handle the power that is produced by a healthy big-block, unless you purchase a T-56 built to run behind the Dodge Viper (V-12, 8 liters) engine. I would suggest the TKO-600, built by Tremec. Your gear-spread will be a little bigger (good, with a healthy 454), allowing you to use more of your engine's RPM band. And then, you'll have the overdrive, whenever you want. In my opinion, there is little advantage of having 6 gears versus 5 gears, for real-world driving. (If you're only racing, that's different. ;) ) The beauty is that you can buy the TKO-600 new, for less than a used T-56, and the thing will survive ANYTHING you can throw at it. :) Just my $.02. |
