new tranny gears

[landyacht67]

Ok so I put in my gears. Acceleration great top speed sucks . Don't get me wrong I knew that would be the end result when I went 3:55s. But here's the question. As much as I would love over drive for my 383/727 combo I don't have that much spare cash. Can I change my 3rd gear ratio from 1:1 to something like 0.8:1? when I shift from 2nd to 3rd I'm revving @3000 rpm in 3rd, 3500 if I'm pushing hard. I figure since my powerband seems to start at @2300 I wont really suffer from having the longer last gear. If that can't be done can I make My 1st and 2nd gears shorter and leave my third 1:1? Then I could go back to 2.89:1 and get the best of both worlds (If this is what I have to do I wish I'd thought of it sooner) . Any suggestions?

It would be easier and cheaper I think to ethier;
Do a gear Vendors Overdrive unit behind the tranny or swap in a GM 4spd auto tranny.
Custom gear work can be done by Liberty or Richmond. These guys do manual trannys, auto's may be possible.

There are no gears involved in 3rd speed in a Torqueflight, the input shaft and the output shaft are locked together for the 1:1 ratio.
Replacing the factory 2.45 1st gear with an aftermarket 2.77 1st gear set ($500) would help, but not that much.
