Building a 69 cuda dragradial car 408/456 gears with dana 60, not sure if I should go with a Powerglide or 727!!!!!!!!!


Have yall slow down with powerglide or what do yall think,, INPUT please


Thanks

My , lightweight all out racing Proflyte Call Dave at Pro Trans, 661-940-7400 for information and pricing, lots of choices on gear ratios and parts Best trans out there when it comes to a 3 speed automatic for drag racing

Looking to make around 650HP and shoot around 150 shot of GAS,

---

Proflyte No problems at that power level, a freind of mine ran one at a lot higher power level in 10.5 Outlaw in PSCA. He won several championships with that tranny, if I'm remembering correctly How about that BobR,yes ot no?

Being a 10.5 tire car I would go glide... it'll be
a little easier off the line(assuming its a 10.5)

Cab Doug runs a glide, I don't think he ever ran a Proflyte. Bob will know for sure

---

Doug ran the Proflyte in the 460 BB N/A car that he won the PSCA 10.5 Outlaw chamipinships in several years in a row. He finally got tired of racing and quit, the car before that and the car he has now has a Mikes Tranny Ultimate glide in it, Mike has sponsored Doug off and on for a long time BTW,I taught Doug less than 10% of what he knows Just like Dominic(Thumperdart) Doug use to have a Duster with a 440 in it That(the Duster) was a long time ago when Jason was young and working across the street at Gil Marine, not running his dad shop, Pettis Performance like now.BobR bought the Duster, he still has it I think, or is that the car you have

The powerglide WILL slow you down, mabey a good or bad thing (I always thought the point of raceing was to go fast ).

The power glide is cheaper, until you have to go through a dozen converters and 1st gear ratio swaps to get it nearly as fast as the 727.

Just don't run a valve body without LBA and the 727 is bullet proof. You will probalby even be able to run a higher gear at the start line unless you are running 1/8th mile. The only reason a glide should be mentioned on a mopar site is by the guys who like to no other reason to recomend one on here

I run a glide in a 2300# race weight car....when it had a 727 it would stand on the bumper. 1.76 gear and a UCC converter. Being a class racer and bracket racer I could care less what the 60ft is as long as it repeats

The Power Glide did not slow me down I just keep getting faster and faster.. Consistent is the word . I don't even have to hold a # just run her out the back door..

The only reason people have "too violent of a launch" with a 727 is because they run too low of a rear gear, they blame the trans when it was there own choice of rear gear that made too much tq at the rear tires during the launch.

---

you set the gear for the max rpm that you want
to run

MR_P_BODY

you set the [rear] gear for the max rpm that you want to run

^^^^ THIS

.

To MrPBody's good advice, I would add only this:
- First order of business is you gotta get the converter right.

Regardless of transmission choice, you have to get the engine into its optimal power producing range and keep it there through the shifts.
Too tight of a converter will not let the engine rev up quickly and at the shifts it will pull the engine down below that optimal power range which will just simply rob you of ET.

It is said that converter choice is more critical with a powerglide due to 1 less gear and the missing torque multiplication, but if you have the wrong converter in a 727/904 you are also just as likely to go slow.

Dave contact: John Urist, Chip Havemann, Sean Lyon, Kieth Szabo....the list goes on and please tell them they are doing it wrong by running glides

Note....this is just a point....nothing personal

As for keeping it in the right RPM range at the top end of the track, most guys with glides are way past the sweet spot in the RPM range when they cross the stripe, they have to compromise the top end to improve the launch.

---

I totally disagree. I run a glide in both my RED and door car and both cars cross the stripe in the sweet spot with out compromising the launch. Look at my signature picture and tell me again I’m doing something wrong.

Quote:

---

Almost every time someone posts how they drive there glide car they say something like they shift at 6000 and cross the line at 7000, the fact in MOST cases is they shift right when they should and cross the line significantly past that same RPM how can the sweet spot be so different from one shift to the next? The truth is it is not and another gear near the finish line would allow MOST cars to accelerate even more before the finish line. All the car cares about at the starting line is the TQ multiplication, a 727 with a 3.23 gear is gonna launch with the same starting lin tq as a glide with a 1.74 1st and 4.56 gear, it is not rocket science, run the right gear to tame the launch and you can still shift at the top end when MOST cars need to. The problem is most guys want to brag about haveing a 4.56 gear, makes up for small .... syndrome, I mean who wants to show up with a hot drag car and tell every one they have a 3.23 gear?

The only worthwhile argument for the glide is that it is a simpler trans. Of course you lose that argument when you have to run adapters and stuff to make it bolt to your motor and car.

---

Dave maybe you should build yourself a time machine that can take you back to the 60's & 70's and then maybe your argument would be valid

I shifted my glide at 7200 and crossed the stripe at 7500 7.90's - 8.0's didn't need a 3rd gear

You are only proveing my point crossing the line higher RPM than your shift point, not as big a differance as most but still proveing my point

Dave,
One point you are missing in your comparison is the converter.
While the choice seems to be more crtical with a Glide, the glide has much better choices. Converter technology, development and size,(THICKNESS) all favor the glide user.

The shallow bellhousing of a 727/904 limit converter choice in those areas, so the extra gear isn't as much of an advantage.

My 3000 lb A body with a small block, small system, and drag radials has a low gear set 904, and just went from a 9inch turbo action to an 8inch J&W. My 2800 lb. Chally with a big block, big system and 14.5 X 32's has a glide that's seen 2 different gear sets, and 3 different converters. I've spent more money in half the passes on the 904.

A simple spacer is available to leval the playing field on converters

The car is a ladder bar car with Qa1 coil/ 315 M/T dragradial

What kind of suspension will the car have and what will the approximate final weight be with you in the seat?

Which radial brand and what size?

Several important factors have been left out to give any real solid advice.

If you go with a glide it had better have a good converter or it will CHOKE the entire combo.

However, with the info you've given I'd go with the 3-spd; just depends.....
