They will shift the best here and the trans will last longer because you will remove any of the overlap in the gear changes. Just be sure to use a quality cooler and use type F oil, It has a better coefficiant of fricton!

My car will be a street car, so I don't want to set it up using the race setting if it'll ruin the street manners of the car. But then again, I have a big tolerance for "street manners."

If your going to race the car I would go with turbo action reverse man vavle body and they work just fine on street too. And TF 3 is not to much for street you just have shift 1965 Plymouth Barracuda 273 M/SA 1970 Plymouth Duster 360/904 10.60s with J heads

I guess that leads me to the following question:

Having never used either the TF-2 or TF-3 kits, for those who HAVE, which one do you folks prefer on a mid-high 12 sec street car???

The TF-3 can be setup two ways, with or without the TP linkage. The choice between the TF-2 and TF-3 is strictly up to the driver....either you want to manually shift each gear or you don't.

That is next to impossible, the 727 by design has overlap. The direct clutch applies while the band is releasing, if the band were to release first then the direct clutch applied you would see an RPM FLARE.

This was my second one i have installed, last time i cranked the line pressure six turns instead on the four they recommend and mine shifted super firm, its the best tranny kit I've ever installed. So my vote is the TF2.

TF3 turns the tranny into full manual, but still retains the kick down linkage to regulate throttle pressure. Stomping the pedal with a TF3 will not "kick down", but in a TF2 it will...if properly adjusted. I have a TF3 in my Demon's 727 and it shifts VERY firm 1-2 and 2-3. Almost too firm 1-2 because under WOT she gets VERY squirrely kicking into 2nd.

There plenty of things that can be done that eliminate ANY overlap in a torqueflte.

This is why the TF is inherently inferior to transmissions (like the TH400) that have no release/apply operation. The INTERNET, the MISinformation superhighway

To say any VB will eliminate ALL overlap is good advertising but not very realistic, more likely is the claim to eliminate excessive overlap. The INTERNET, the MISinformation superhighway
