My dad and I are building a 69 Camaro and are trying to go with a 6 speed instead of the factory 4-spd.

We have an M-21 4 speed or a turbo 400 out of a 67 Caprice that we'd be interested in working something out with.

I'd say the TH400 could use rebuilding, but we never really drove on it.. We got the M-21 with the Camaro and were told it had been rebuilt.

We haven't even gotten to putting the motor and transmission in yet, but we are planning on going with a T-56 out of an LS1 f-body.
