There aren't really guidelines, just opinions and perspective really.
Most people say if your car weighs around 3000# or less and/or makes a good amount of power it would benefit from a glide. Taller first gear helps prevent wheel spin, and as stated it removes one shift from the equation. Powerglides typically also react quicker and work better with that kind of power in front of them.
If I was in your shoes, I would purchase a good powerglide with a Reid/Dedenbear case and never look back.

I'm putting together a 69 GTX. Car is currently at 2880lbs. Race weight should be about 3050. Engine is a 535 inch Hemi with ported stage V heads. This engine went 9.63 at 138mph @ 3800 lbs in the last car it was in. Should I go with a torqueflite 3 gears vs powerglide? Power glides are sooooo much $$$$$cheaper. What do you guys run with your combos? Thanks!
Are you spraying it coming off the line... if you are then go with the glide... the torqureflight and its 1 gear is much lower but on a big power lite car might break the tires loose (if spraying)... I run the 727 but with a SB but get a 1.19 60' N/A

i went from the three speed to the glide. purpose is the glide has a tall first gear that works better with the 28" or 29" tall rear tire.will help slow the tire speed off the line. also when looking at the graph you can see a spike in rpm every time it shifts. my thought was to take one of the shift spikes out of the equasion. like said earlier, i choose the glide for racing. if it were street than i would reconsider.
Actually if you think about it the glide would increases the tire speed and decrease the torque applied to the tire. The lower 1st gear of a 727 would decrease tire speed but multiply the torque applied to the tire.

well now there are multiple gear sets for the 727 2.28/1.45/1 to 1 2.24/1.39/1 to 1 2.10/1.39/1 to 1 in straight cut gears mighty strong way to build a 727 right right off the bat for hemi power?? Bottom right on page 22 and straight cut on page 23 http://www.aandatrans.com/images/2010_Web_Catalog.pdfstock gears are 2.45/1.45/ 1 to 1 lower sets are 2.74/1.54/ 1 to 1

Triple Threat, What are the advantages and what are the general guidelines where one would chose the glide over the torqueflite? This will be a fun track car that will bracket race 6 times a year.
The best way for me to respond is to post the history of developing my current setup with a Torqueflite to give you an idea of what to look for. So here goes. First, I like the harder launch of a three speed. First combo- 106 wheelbase, 17 inch engine setback, 30 inch ladderbars, full 2x3 frame/tube cage, 50/50 weight distribution, 66 inch long wheeliebars, 499 cubes, 725 hp,9.30s at 143 mph. At this point the car started to have troubles with consistant 60 fts. To help solve this problem I put in an anti roll, good double adjustable shocks, and the biggest tires I could fit, for a trap rpm that matched the shift points. The 60 foots were much more consistent, but the wheelstands were so violent I was loosing consistancy by unloading the rear tires, and often not going straight on the launch. At this time I also went to a 528 cube, 440-1 head alky injected motor. The car responded with 1.27 to 1.29 60 fts, 8.80 ETs, and the same issues with wheel stands and inconsistency. I was advised by some smart racers to put some weight up front, and made an extreme move to 53 percent on the front. I had the corner weights set, and the car responded with VERY consistant 60 fts, and if they were off, it showed 330 numbers that were spot on. (The 60 foots are now 1.248 to 1.2500 on a good air day) The reason is the car still pulls the front as high as I will allow, and the landing and where the car rebounds can change where the 60 ft clocks trip. (tires, or front valance) Looking back over the last several outings the car has repeated within .002 to .005 on every 1/4 mile pass on the same day. This is obviously on a well prepped track, so keep that in mind if you plan on serious bracket racing on a marginally prepped track. In that case, the glide will definitely have an edge, although I am not sure how much. Good luck on your choice. No choice is correct, just what you want to run for your own reasons. Myself, I like an exciting ride, and the ability to show the nay Sayers that a Flite can be very consistant!

Helical cut gears...Bottom right on page 22
http://www.aandatrans.com/images/2010_Web_Catalog.pdf
stock gears are 2.45/1.45/ 1 to 1
I just talked to Rob at A&A about the helical cut 2.28 ratio gears. (since the $2,000 straight cut are not in my budget). He thinks they are fine for my 750hp (estimate), and the 4-pinion version is only $725 (p/n 22753H4AT). And under 1000 hp might be OK.
I am seriously thinking about this for my car. 3250 race weight, 1.27 sixty foot, 9.20's ET, 511 CID wedge. I am marginal with my chassis, and this might calm things down just enough to work with old tires and marginal tracks. My chassis is fine with newer tires and good tracks.

I like the ride too, and enjoy the 3 speed. Has it cost me a round or two? Yes. I've driven many cars for other people too and the glide equipped cars still haul azz but the 3 speed is nice and I like it.

Depends on what you are doing with the car. If you are an ET chaser then by all means go with a 3 speed. Wheelspeed is where it's at to go fast. Now if you are index or bracket racing then by all means get a glide. One less variable in the equation. Lots of misconceptions about running a glide, the biggest one I hear is about weight. I ran my 3470lb Valiant with a glide and had zero issues. But it only went 9.0's on motor. FWIW we went 8.80's(8.77 best)with the big tire car with a 572" hemi at 3000lbs with no transmission issues. The wedge motor has proven to be less kind to them
