:shitbrick Will you adopt me or something? Throw me a couple grand. lolYes but a lot of guys don't plan on making 2000hp down the road with their cars

sorry but you are mistaken. The powerglide is THE strongest automatic period... Less parts to break in a powerglide and they are extremely easy to build.
Also im pretty sure all the 2500+hp cars are using glides....
You are right about there being less parts to break, but the fact is that even though there are more parts in a TH400 the parts in a TH400 are stronger than the parts in a Glide. The main reason race cars go with a powerglide is because it's lighter, and less parasitic. The powerglides in race cars are bulletproof, but that's because they are built that way. It takes a lot of money to build a glide to be bulletproof. That's why full race glide transmissions are $3500+ Small example: Here's the driveshaft yoke from a PG and a TH400 side by side.. The TH400 is on the right..

Strength of the transmission regardless, the TH400 would me more desireable on the street. Typically turbo RACE cars prefer the powerglide because of the tall first gear, making it easier to get off the line. We sit at the line and spool before we light the 2nd bulb, so low end torque isn't an issue at the track. On the STREET however, the lower 1st gear in the TH400 is desirable to get the car accelerating quicker. With a glide, taking off in first is like taking off in 2nd with a Th400. The turbos come on quicker with more rpm in 1st gear with a TH400.
In fact, the turbo of choice for most full race 2500hp+ cars is the Rossler Turbo Glide. It's basically a 2 speed TH400. It has the stength of TH400 parts, with tall first gear of a glide.
Here's an example of a 3500+hp car with a TH400:

Yokes have nothing to do with how strong a tranny is, you can always change the yoke to a bigger one. Turbo 400s are good but glides are stronger. I don't know who builds your transmissions but a built turbo400 is more expensive to build than a glide.You are right about there being less parts to break, but the fact is that even though there are more parts in a TH400 the parts in a TH400 are stronger than the parts in a Glide.

Dude, just google it.. lol
I'm not saying a glide isn't strong enough.... I'm just saying that on the street the TH400 would be a better tranny, and trust me YOU CAN'T BREAK IT. If your car was race only, I'd tell you to put a glide in it... On the street, if you love the equivalence of taking off in 2nd gear all the time, low rpms in first gear, and slow turbo spool, then by all means buy a glide...
Track - glide (higher first gear is great for scrubbing off torque helping a small tire car get off the line, eats less horsepower, is lighter.)
Street - TH400.. (a turbo car needs that lower first gear for spooling. We don't sit on transbrakes on the street. When you race on the street, do you launch in 2nd?)
I have a race car, and I have a street car. The race car has a glide and makes around 2200 horsepower at the flywheel. I run a BTE top sportsman glide with straight cut 1.69 planetary. That tranny cost right around 3700, and the converter cost right at 2,000. The street car has a TH400 from JW.. Straight cut gears and they cost right around 2000. Converter is about 1000. Both are turbo cars, and both are fast.. My old race car had a th400 in it, but it was street driven. It made 1284 at the rear wheels, and ran 8.40's at over 170.. Launched on the transbrake every pass, and I never broke it. Th400's are CHEAP to build. That TH400 with straight cut gears, trans brake, and ultra bell cost me $1350... The glide in my new race car cost $3700... I'm not trying to mess you up. I am speaking from experience. The truth is I have two cars with TH400's, both with more power than your cobra, and I've never broke one. Your statement that a TH400 would never live behind your setup is just false.

for my( at 99% street car) will be putting in a Th400 with a transbrake for fun lol So you build your own TH400's Mean or buy them?

sorry but i dont know where you are getting your prices from. A TH400 from mikes, or CK transmissions is well over what you are estimating. Thats great that your cars ran great with them, but you saying that a th400 is stronger than a glide, is completely false.

haha I need a passport to do that..no thanks lol
A glide has to be BUILT stronger than a TH400, but there's not a single race car out there with a stock powerglide planetary out there. There are NUMEROUS race cars out there with stock TH400 planetaries. The TH400 is a stronger production tranny than the glide. Just trust me on this.
Here's some GM history... Gm releases the powerglide.. GM releases the TH350 (which in physical dimensions is identical to a glide) to replace the powerglide. GM releases the TH400 as the HEAVY DUTY transmission to go into heavy trucks and towing vehicles, because the TH350 isn't strong enough. From the factory it is built with stronger beefier parts than a powerglide.
Just go to BTE's website and look at their TH400 tranny's and their Glide's... The glides are over 2x the price of the TH400's. Find me a race glide for less than 2k.... Race TH400's are everywhere under 2k..
I am a GM guy... I've been racing chevrolet's for over 10 years. When looking into a GM transmission, you might want to ask the opinion of a GM guy, and not believe everything you read on Mustang websites.
I have actually run a TH400 with STOCK PLANETARY with full manual shift kit, and brake launching a turbo car (only mods being valve body and ultra bell) and it didn't break. I upgraded it to straight cut gears for insurance, and ran it for two seasons with 1300hp in front of it, and then sold it. It never broke... Here's the car launching on the brake on 295 radials at 3460lbs:

Lol I understand what he's saying. I don't compare stock **** ever, because I like to overkill everything so I was saying I was going to use a built to hell mikes powerglide which is the strongest. That's what Nelson uses in all his cars and he never broke them once
