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. ![](/ubbthreads/images/graemlins/smilie_help.gif) 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... ![](/ubbthreads/images/graemlins/Twocents.gif)

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. ![](/ubbthreads/images/graemlins/bow.gif)

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.

You can play with stock cases and gearsets all you want Monte and that's fine if a guy is local and wants to take chances. When a guy is not your neighbour your not doing him a favor by suggesting to build a trans for 700HP out of a trans that was designed around 190HP. Builds have a lot of variables and the prices will reflect that in most cases. You can say 10 clutch drum for example and I can say which one? Those not knowing can get them in many different forms which some are a bit junky. Planetaries are the same as there are too many variables then we get into pumps, VB's etc.
This is why the prices vary. Now if you think a stock case is good or "you are getting away with it" that's fine but if a guy was going to build a 2000HP motor, would you use a stock block? I hope you can see where im coming from here. Im not saying you can't do it but in many cases its just foolish to try.
Hutch
Have always used stock case..
3000# 900+ hp..
I use a good turbo input shaft good 10 disc clutch pack and a good aftermarket gear set.
Have only broke 1 gear set and that was an aftermarket one.. Go figure.. Never broke a 1.76..
To each his own.. Been using a glide since 1993.. ![](/ubbthreads/images/graemlins/1343795-scratchchin.gif)
I have 3 back up transmissions just in case.. Cost is less than 1 Super Duper trans.. ![](/ubbthreads/images/graemlins/laugh2.gif)

Oh, I am not arguing the point Hutch and I already said that I would NOT do it myself, but I know guys that have
Monte
That say's a lot right there You would NOT do it yourself,but will recommend that others do it,and you base that on what someone else does.Our opinion was based on what we do and our experience and from opinions of people we trust like Craig at Coan and Paul at TA.If what you say is the Facts according to you then we don't need billit drums and LBVs in our TFs either.So no matter what weight or HP level just take your word that others have done it and if anyone listens to you will be safe and satisfied.As far as your offer to sell me PGs at a great price I would rather deal with someone who would recommend what I need for my particular application and with my safety in mind not recommend what "they know others" have done.So don't be looking for any trans orders from BGR anytime soon. ![](/ubbthreads/images/graemlins/thumbs.gif)

So while everyone is on this topic, does anyone know what it cost to get custom gear set for a 727 or 904. The reason I ask is because I know Comp Eliminator guys do that from time to time in the faster classes to get better ratios so I'm just curious of the cost involved.

Actually Dave and the guys at Protrans are working on a 3 speed for the higher torque top sportsman type stuff right now. The current stuff they use does not hold up well under high torque loads. A buddy of mine has been testing the prototypes. I plan to use my current Rossler TH210XHD for TS duty. And as Monte pointed out Protrans nor Rossler are cheap

Do you already have the 727? In our experience, with some decent internal parts it'll be fine. Talk to Jon at CRT. Our's is very low maintenance, rebuild every 250 passes or so.

Hey Monte , take it easy. There is no hollier than thou anything happening here. You stated he could run a stock case and gearset in your first post of course to save money and all I did was try to shed light on trying to "get away with something" is not always the best choice in the long run. I don't care what you are getting away with as your not in the trans business except when you can make a buck on a drop ship from a vendor you support. Im down here in the trenches every day dealing with this stuff as are you with nitrous so I will tell you I have more exposure to it.
Not here to argue with anyone, just to raise a few valid points. If you have a problem with anything I have pointed out Monte or think I singled you out in any way, you are welcome anytime to discuss this with me personally as I had no ill intent. You know my number.
Hutch
Nothing I said was directly aimed at you Hutch. There was another accusing me of putting people in danger with what I said and I didn't appreciate it. Even though one of his own customers has been running that very setup with no issues. Seems he should be advising his own customer of the inherent "danger" if there is one. I have no issue with you, never have.

I want to Thank each and everyone of you that have took your time to try and help me. ![](/ubbthreads/images/graemlins/thumbs.gif) I did have a bit of luck,a Friend of mine is going to a bigger engine and was wondering if would be better of with a Glide also an offered to let me try his 727.He has been running the Foot-Brake class and it does not have a trans brake but I can use his converter as well.But even without a trans brake I should be able to get an idea of how it works.Thanks Again everyone for all the Great Advice. ![](/ubbthreads/images/graemlins/thumbs.gif) PS when I try it and find out how it works and what I tink I will post it and let everyone know.
