JW ultra bell will fix that
I had a 727 from Transking with transbrake and a reactor products flexplate in the Rambler was solid but car would have been faster with built 904.

Right. If you are looking for a little extra, a 904 behind a 360 in a drag truck might get you there. It would be expensive but a interesting comparison comparing time slips.

I wish a member could post the Car Craft torqueflite article its was very interesting and I remember a comment about if one was trying to set a record a pro series 904 would get it done and more efficient etc its our
POWERGLIDE !!!

I bet A&A has some trick parts for the 904 these days !!
Glides are a very popular drag transmission. With the right converter and rear gear, a light car only needs 2 gears. Glides can be easily built damn near bullet proof and cheap. I had a buddy (Chevy guy) that was into glides. He would build one in his race car trailer during the races between rounds.

Honestly with the correct tools I can't see not being able to rebuild a 904 or 727 extremely quickly...
Now I've had a turbo 350 apart and that was a nightmare...
I've also done a 63 Ford ford-0-automatic and that was a two-speed automatic but it only had like two clutches in it LOL...

Yes it was never designed to be what its NOW famous for and its very popular with as you mentioned the Lite weight vessels.
rebuild and built are two different things, though. It's kind of like doing a valve job vs doing a 5 angle valve job plus port work. Massive difference.
Most of the fast cars running a glide only have about one or two 12 dollar items in them that are GM.

Yes indeed both are what we have and suit many many roles !!
I have a 4 gear front & rear planetary 727
Factory in my 886 Power wagon it takes a lot of effort from the mild 318 to propel vessel but its solid and always works flawlessly and will live a LONG time.
I know what it's like to have a powerglide in my truck. When I had 2.71's with a 31" tire, I only used 2 gears

If this guy is "building" 2-speed power glides in between rounds he's likely just freshening them up and changing the same parts he had in there...

Also building a high performance transmission is just putting more durable parts in with the add of some custom parts but not much machining..
That sounds like a lot of work to make a pass... LOL

The machining done on transmissions is likely in the drums to add more clutches and I've heard something about a removable sprag which I can only imagine would be machining the back of the transmission... Again a lot to go through for shaving a tenth here or a tenth there...
I don't claim to be a transmission expert, but I know for a 904 to live behind a 600-700 hp or more engine, there is something to it !!!

Maybe not as much as you think but quite a bit of money for those parts..
I don't think the design changes much just the quality of the parts...
Billet this and hardened that and treated this and Kevlar that... A lot of high-end parts and then when you say live nothing lives for ever... I know AAR cuda usually gets I think he said around four seasons or so on his transmissions doing low tens.... I don't think he does a whole lot special...
Yep, any transmission.

Honestly though I'm going to go back to what I first said...
$113 heavy duty rebuild kit and a $90 trans go to shift kit and put the full command feature in...
Nice and easy on the budget and a good piece of mind for the future...
I would try and capture 3 tenths somewhere else..
