Dave,
One point you are missing in your comparison is the converter.
While the choice seems to be more crtical with a Glide, the glide has much better choices. Converter technology, development and size,(THICKNESS) all favor the glide user.
The shallow bellhousing of a 727/904 limit converter choice in those areas, so the extra gear isn't as much of an advantage.
My 3000 lb A body with a small block, small system, and drag radials has a low gear set 904, and just went from a 9inch turbo action to an 8inch J&W. My 2800 lb. Chally with a big block, big system and 14.5 X 32's has a glide that's seen 2 different gear sets, and 3 different converters. I've spent more money in half the passes on the 904.
A simple spacer is available to leval the playing field on converters

If it is all about ET in a heads-up class, a 3 speed will allmost allways be quicker, especially with some nice friction reducing, and lightweight parts, but plan on high cost and frequent maintenance.
If it is shoe polish racing, reliability is way more important than a few hundredths of E.T. Either the 727 t-flite or GM type 2-speed can be made nearly bullet proof with 750 horsepower or less, for a reasonable amount of cash.
As far as glides go, most good ones, [for big HP engines], are not cheap and have very few GM parts still in them anyway, so keeping a t-flite just to be a Mopar purist and not have a chevy trans is crazy. My JW 2speed is mostly aftermarket, The 2 main GM parts are the front pump cover and tailshaft housing. The case, bellhousing, planetaries, input-output shafts are super beefy aftermarket parts. I don,t call it a power-glide, I call it a JW 2speed.
I am in a similar situation as the poster, except I shoe polish race. I am going from a 650hp engine with a near stock 727 with t-brake and 4.10 rear gear/ 15"x33" tire in a 2500lb. LeBaron, to a 800hp engine. My thoughts are to go with the JW 2-speed and switch the rear gear to 4.30. or do I beef up the 727, ultimate drum, steel 5 pinion front planetary, super sprague, aftermarket input shaft/drum assembly, etc. and go to a 3.90 gear. either way I will have to buy a properly matched torque converter.
In my case I am leaning 2-speed/4.30 because one shift should be more consistent and allow me more time to eyeball the car in the other lane to drive the finish line better, knowing the finish line rpm will be a few hundred higher. Closest 1/4 mile track is 4 hrs away so mostly 1/8th mile use anyway.
In the posters case I think I would go with a well built t-flite

Building a 69 cuda dragradial car 408/456 gears with dana 60, not sure if I should go with a Powerglide or 727!!!!!!!!!
Have yall slow down with powerglide or what do yall think,, INPUT please
Thanks
The car is a ladder bar car with Qa1 coil/ 315 M/T dragradial
What kind of suspension will the car have and what will the approximate final weight be with you in the seat?
Which radial brand and what size?
Several important factors have been left out to give any real solid advice.
If you go with a glide it had better have a good converter or it will CHOKE the entire combo.
However, with the info you've given I'd go with the 3-spd; just depends.....
