Depends on the weight of your ride too I guess. My buddy runs a 727 behind a approx. n/a 1200hp hemi in a 70 Roadrunner @ 3700lbs running high 8's. And so far it hasn't given a cramp. Give John (CRT) a call to be sure.

Go Lenco, or Bruno, if nothing else, the ease of picking your gear ratios.

we run 1500hp with a n/a hemi with a 727 with no issues
what rear gear and 1st trans gear with that much power dont seem like you need much starting line ratio?

A chevie friend has ran several Turbo charged combinations. He has several transmission options. He has tried the glide several times but says he cannot build boost quick enough with the glide. He often jokes and say he does not make enough power for a glide. He uses a turbo 400 with aftermarket ratio's. He has sense went to a crank driven blower and still runs the 400 but takes off in second now.
I would have no problem running a 727 with your combo. Tranzact has a new gear ratio available. No matter what you do if running a 727 I would recommend running a 1" spacer between the engine and transmission to allow room for a 1" deeper torque converter. I found when switching to a powerglide that the extra 1" in dept of the chevie derived converters is the secret of why these chevie transmissions seem to have so much popularity in the high HP ranks. If doing it all over I would still have a 727 in my car and possible with a stock ratio 2.44 first gear. Something to consider if running a 3 spd behind a turbo would be to have the 1st to 2nd gear change shifted in relation to boost and not RPM. Just a thought.

I just sold my 727 from behind my turbo'd 572. Thought it would be a good idea to get rid of it before I broke it.
Went to an extreme automatics Turbo Glide, best of both worlds with the capability to handle whatever my engine can make.

I'm going glide behind my 468-turbo motor. My thoughts behind it were: 1.A lot of people use them and build them so parts & service/repairs are easy to come by 2.The taller 1st gear will absorb some of the initial shock of a Turbo Motor to the car and tires coming off the line. 3. Price of course 4. Less shifting I got a heck of a package deal on a used but freshened up set-up. Take a look at ATI's line up of PG's that come with warranties.
