My big SB made 778 on the dyno. My cars been 5.66 @ 120 in the 1/8 w/ 3.91 rear gear. My 904 works ok with LOTS of after market parts. If I had it to do over I'd put a glide in it. If your car is fairly light ( under 3000) the glide should be as quick or quicker. Mine has the following billet input and out put shafts. Aluminum front drum,after market front clutch spring pack. Trans act brake. Rollerized assembly,lightened sungear, rewelded planetaries, needle bearing out put shaft support, Deep Pan. It has a 2.45 low gear but I've tried a 2.28 after market gear set.I've broken lots of parts especially with the big SB. At 600-650 hp you might not need the billet shafts. The rollerized and lightened rotating assembly isn't worth much ET. I would always use a rollerized output shaft bushing in almost any application. Again if I had it to do over I would use a glide, that's what my new Daytona has.

I snapped the output shaft clean two years ago in my 904 (haven't race in a year and a half) and replaced with another stocker that I had, but its only a matter of time in my opinion...that pass was on motor too! wasn't even spraying! I just picked up to 1.76 glide cores for $100 yesterday....904 is coming out soon for a freshen and then bye bye, so I'm sure you know my opinion

One thing I feel I should point out for guys who may have ran 727s or 904s for most of their lives, and are just making the switch to a glide.
A glide in a high horsepower combination is a high maintenance option, that requires nearly all aftermarket parts. Now trust me, the aftermarket support is awesome, the converter quality and choices are great, but for many 727 racers, it's a bit of a shock going to a trans that is expensive, and requires attention regularly.
Most glide racers keep a "pass count", and rebuild at regular intervals.
I had a friend who was considering the swap a couple months ago. He wanted a Glide with a gear vendor, for a Drag Week car. I sat down and wrote out all the parts I recommended for his application, but the 7K price tag scared him off.

I have an aftermarket input shaft and pump gears in my 904, although I have never broken them I just uprgaded due to advice on this board. I've recently purchased the steel drum which takes more clutches, and has the big piston, for the next freshen up. I have the Griner LBA Brake, and other than burning up the front clutch pack, I haven't had any breakage...but I'm only at 3100 lbs.

Also, a glide built RIGHT doesn't require frequent maint, at least not in my experience. We broke two gear sets in all the years we ran a glide behind 2000hp. No problems with clutches at all

After you buy the Ultra-bell the powerglides are very cheap to run. My Friend and I just went through mine 2 weeks ago after it slowed up .07 and my Son said the 1-2 shift was weak. He went ahead and ordered the parts (clutches, band, and a couple of seals) so we would be ready. He came to my shop and we tore it down and the band was the issue but even after 4-5 years the clutches looked GREAT so we reused them. I installed the band and new seals and we put it back together. Total cost for the parts were under 70.00 and I have new clutches on stock for next rebuild. I broke one stock 1.82 gear years ago (125 passes) but never hurt a stock set of 1.76 gears. Now for my small tire car I went ahead and bought a set of aftermarket 1.69 or 1.64 gears for it that were pretty expensive (around 1200.00) so I hope they hold up.

Lets agree you can do a good trans for 3500. 1k for a quality converter, 2500 for a gear vendor, new shifter, new drive shaft. It adds up.
Most of my SST/SG buddies freshen them every 100 to 150 passes. Perhaps they kill more clutches because they come off the stop in high gear.
I ran a stock case Glide for many years, but nearly everyone starts with an aftermarket case these days, we typically run the JW stuff.
