I have a 69 RoadRunner I am setting (trying)for the 6.0 class.I am thinking it should be in the 3200-3400 lb range,the 572-13 540 engine should be between 850-900 HP with 1 1095 King Demon but have a Tunnel-Ram and 2 1095 King Demon's on Race-Gas(I have gas set up not alcohol so that what I will run).Just hoping I will not have to use the Tunnel so I will not have to make any changes to the hood.It is a 4-link car with 33" tires and will have a 4:56 gears in the rear end. I have never run this type engine in a car this heavy.Which transmission do I need to go with the 727 or PG? I'm hoping some of you with cars like this can chime in and help me pick the right trans the 1st time.I want which ever one will make the car run the Fastest.I lean toward the glide because it is cheaper,but some what afraid it might not 60' leave hard enough with a glide. Thanks

My Chally weighs 3,400 with me in it. Yes, its a dog off the line with a powerglide, but being a dog off the line isn't all bad. It makes it easier to set up the suspension. Less likely to spin the tires. I have 800hp and have run 5.91 best. If you want a magazine cover, wheels up launch use a 727.

A glide is not cheaper. You don't want a stock case so that's $1,200 for a case. You probably want a 1.80 straight cut, that's another $1,000. It all adds up.
How you figure. I can sell you a PG in a Dedenbear case, 10 clutch alum drum, roller bearing, good tail housing, 1.80 straight cuts, billet servo, ringless input, deep pan and a Pro-brake, that will live behind 2000hp in a 3,000lb car for $3200.
Now, does the OP NEED a trans that will hold 2000hp, probably not, but for what HE wants to do, a glide WILL be cheaper, because he can use a stock case and the factory 1.76 gear set and be just fine. He will need a good input, a pro-brake and a few other things. But overall the trans will be cheaper than a 727 with the needed mods for what he wants to do.......Plus, the glide will be lighter and react better in a heavy car on a pro tree. There is no TF brake that even approaches the quickness of a glide brake. Lets get away from the Mopar vs Chevy side of things and see what will work BEST for what he wants to do.

I know of quite a few heavier cars running glides with good success...

I just switched to a glide.Car weighs 3,400 with me.In killer air with 160 lb. In trunk it would run 10.07.With the ballast removed and the glide in it went 9.83 with killer air and a slight tailwind.Now the glide also has a brake where the old setup was footbraked with a 2 step. I think with as much power you have,a glide would be a way better, more manageable choice.Sure, you may lose a couple hun in 60 but you'll pick that up because the glide is lighter and robs less power imo.

I think a glide will work very well in the car just don't buy junk or improperly built stuff or it will just slow you down. I heard someone here rambling about stock cases and stock gearsets and that's bad advice all around. If you get into something like that you will wish you never saw a powerglide.
Hutch
Yeah!!! what he said.Put a stock cheap PG behind 2000 hp and a 3000# and or even a 900 hp 3500# car and pull the pin The last PG I priced out for a 1000 hp,3100# car was a Coan "Ultimate Big Dog Glide"@$5000 +$1300 for a converter.Some of their Superglide-XST trans run 0ver $8000 The cheaper glides are 6 clutch and 300m alloy shafts with 1.76 and 1.82 ratios std cases run aprox $1400 and up,depending on the options+ the converter.
You are shopping at the wrong place then. I listed above what you can get in a $3200 glide that WILL live behind 2000hp in a 3000lb car on Drag Radials. How do I know, because we have done it for years. Serviced the trans ONCE a season. NEVER, I repeat NEVER broke a 1.80 straight cut gear set in the car. And NOTHING is as hard on parts as a drag radial car. The only reason the glide came out was for a 2 speed Turbo 400 with a 1.48 low gear.
And while I ultimately respect Hutch and his opinion, the power glide stock case is not weak. Cut the bell off and put an aftermarket bell on it and the trans will be fine. Plenty of stock cases out there in some REALLY high HP stuff. Shane Stack has a stock case in his 3250lb twin turbo car that runs 4.30s. Been it in for years.
Every time a glide is mentioned in a Mopar, people get up in arms and start talking about how expensive it is, same as the 9" Ford argument. CAN you spend $5000 on a glide, you bet, do you NEED that in every car....NO.
To the OP.....you are in north Alabama. Run down to Muscle Shoals, talk to the boys at PTC. They will set you up with what you need and it WON'T cost you an arm and a leg
Monte
Monte,no one is disagreeing with you,some of us are just sharing our opinions based on our information.My pricing and recommendations are from Craig at Coan.The basic trans are fairly cheap but once you start adding options like the bells, cases,straight cut gears,10 disc packs,low gear ratios,super sprags,bolt on billit output shafts and the host of other options then the cost adds quickly.Basic PGs are realitively cheap costing from $1000 to $1700 depending on options.Race converters run from $600 to off the charts.I don't think anyone is being argumentative,just difference of opinion and sharing of thought and recommending based on that.If we all think the same,then none of us are thinking.We run PGs in a few of our chassis cars as well as Ford rearends.If buy sharing our opinion upsets anyone,we apologize.

One thing about the powerglide is there is so much good stuff for it. The reason I feel the heavy case is a must have is because the blankets and shields are such a hassle. What we need is ATI to come out with a case for the 727.

Monte,
Would you feel confident running a Stock Case glide, Ultra bell, Stock 1.76's, Trans Brake and a few other basic upgrades behind a 700 hp, 3300# bracket car? Something that see's 250 1/4 mile laps a year.
My understanding is the first weak link is the stock planetary, 1.76's being significantly stronger than 1.82's. People claim to break either with anything from 500hp on up, others live in 1000hp, lighter cars for years.
At what point is the stock case no longer good enough?
Personally I like to overbuild things and would opt for the $3200 option you have mentioned. Just curious how far you would reccomend someone take one.
