Two part TH350 overdrive question

hey experts,

Got two questions. First, I've heard (only through rumor) that there's some kinda overdrive kit you can put on a TH350 that lowers the final drive ratio. I guess it would be something that you could switch on and over intermittently, or at least change before you take the car out. Am I making any sense here, or is this all just garbage that I heard?

Second, I want to switch a 12 bolt for my 10. Is this a pretty common swap? What are the changes I'm going to have to make for an f-body car. What about brakes?

Thanks everbody-

Gear Vendors makes an overdrive unit that replaces the tailshaft of the 350 trans. Would also enable you to have 6 forward shifts. Very nice unit but expensive. Around $1500 not installed.

Swapping from a 10 bolt to a 12 bolt rear is a common swap.
