Transmission Swap - How big a Job?

I've got an early stock Superformance with a Tremec 3550. 4th gear is 1:1 and 5th gear is 1:0.68. The jump from 4th to 5th is too big. I would like to replace the 3550 with a Tremec, with 4th being 1:1, 5th 1:0.80 and 6th being around 1:0.62.

So what's involved here? Is it worth it or should I just live with the current setup? Besides the transmission, what else would need to be replaced? Which Tremec would you guys recommend? Can Classic Concepts on Long Island do this for me? Vintage in Wallingford?

Bob
