Six speed upgrade

Has anyone put an Ultima six speed in a four speed frame, mated to a Shovel head?

My local wrench told me to stay away from Ultima transmissions. I just installed a revtech 5/4, works great. ( If you can find one at list price). Frank

     It can be done but it is a lot of work, you have to use a soft tail primary and starter set up. I done one years ago it ended up working great. Is it worth it the is hard to say.

Thanks Buglet, did you have to modify the frame. I'm aware of the primary upgrades.
