I never thought I would have to ask a question about running a Brand X tranny in my car, as my Father would beat me senseless...but it just seems to be the safest alternative to a Lenco or something like that... The car is an all steel 72 Duster with a full cage. so I am guessing around 3400lbs but could be wrong The engine is 500cid B1 motor with an F2 procharger, or possibly a big 106 mm turbo...HP is going to be over 1000 and I really seem to be fond of my feet as well as the cars floor-pan, windshield and even doors as shown could all get damaged in a recent thread. Is the glide something that would even work in a car that heavy, or will a good 727 from Mr. Cope an option. Thanks in advance Josh

How do you plan to use the car?

Either could work for you but I think you'll be happier with the 3 speed for mostly street driving. That said, you're aiming for over 1,000 hp and while a 727 will hold that the closer you get to 1,500 hp the better choice the glide becomes. If you ever plan on stepping up the power (which is easily done with boost) then you might invest in a well built glide for the long run.

My Gear Ratio is also a concern...I was instructed to run a 3.54 with a boost application, I wonder if this will hold true with the Glide and not a 727
Both trans have a 1:1 high gear ratio, the 3.54 is for the rpm at the top end and that will depend on tire size also

If you do the math concerning torque output to the rear tires, the converter will roughly double the motor torque by multiplication, then times the trans ratio times rear gear. A 1400 hp motor will put out over 1000 ft lbs torque ,so lets look at it. 1000 tq x 2(converter) x trans gear 1.8 x rear 3.54 = 1000 x 2 = 2000 x 1.8 = 3600 x 3.54 = 12744 ft lbs at the axle. If you run a 33 inch tire you then convert to track thrust by 33/2 = 16.5 " radius x 12" (foot lbs) =9268 lbs of thrust at the track surface. Divide by running weight to get G force. 9268 / 3500 = 2.6 Gs. No street in the world will hold that, and it will be just right for one hairy ride down a sticky track!

If you only plan on a 28 inch tire with that kind of power, better get lots of insurance. Car insurance, long term disability, life, to name those that come to mind. My measily 900 hp with 33.6 x 15 slicks 3000 lb car has spun the tires at 125 mph in high gear on a slick track. I can't imagine trying to hurd that kind of animal down the track.

Powerglide would be the best for what you are putting together. My car is 3450 and I run a powerglide. Its a nitrous motor and I'm running on a 295 M/T drag radial. The ATI Supercase is probably the best bet for switching to a p/g in a Mopar.

Glide, Caddilac lock-up converter, big front drum, and an Ultra-Bell should do you just fine. You have plenty enough horsepower and torque to overcome the "weight" issue, and back in the early '60's there were lot's of GM's with glides in them.
