Join now! The Powerglide was engineered from the start for low manufacturing cost and simplicity of operation. Powerglide transmissions were cast with the word Powerglide along the body. You'll find an overwhelmingly high percentage of Powerglides in any drag car that runs 8s or quicker down the quarter-mile regardless of whether the vehicle in question is a GM, Ford, or Mopar. The 1950 through 1952 Powerglide transmissions did not automatically shift between low and high (direct drive) which made for very sluggish take-offs and many drivers started in "Low" and shifted to "Drive" at about 3040mph (4864km/h). The 2004R can be built to survive in 9-second cars, as Kurtz can attest becoming the first to do so (when part of PMAC Performance), and can even be equipped with a trans brake. The Powerslide,, a 2 speed tranny with lots of converter slip. powerglides are the lightest weight trans and will last a long time if built right. The Turboglide, only offered with V8 engines, was more expensive (by about $50) than the Powerglide and did not have wide acceptance, in part due to failures in 1957-58 models, which were addressed by a significantly upgraded version for 1959. Home; Price lists. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada.

Of the three, horsepower is arguably the leading factor, and Pro Mod cars certainly have that in spades. ring gear to the reverse pressure plate is totally But as stated you will need to axle code 2-3 letter suffix code or you can open the rear and check the pinion head it will also have the ratio stamped into it by listing the ring tooth count and the pinion tooth count and part number of the pinion gear plus the date usually. Therefore for maximum drag racing applications, the 1.82 setting is not perfect. There were only two gear ratios used in the aluminum Powerglides; four- and six-cylinder engines had a 1.82:1 low gear with a 1.00:1 high; reverse gear was 1.82:1.

Meanwhile, the rear axle ratio was reduced from 4.11:1 to 3.55:1 to manage driveline noise and harshness. They were introduced in Buicks and Cadillacs the previous year. Variants of the Powerglide were also used in the Corvair and Pontiac Tempest transaxles, and one of the final applications was in the subcompact 1971 Chevrolet Vega. It was available on the Nova four-cylinder engine, and on the Turbo-Thrift Sixes for Camaro as well as Nova. type. Now there are large cubic inch race engines that make good torque and horsepower at higher numbers. Actually, no Powerglide was available in 3-speed. Meanwhile the 'Glide's taller 1.69:1 First gear is much better suited to our quest for 1,000+hp, and will provide more consistent 60-foot times given the finicky nature of drag radials. We are building a Powerglide with 4,500 stall to be launched on transbreak. originally a 3-speed. is a 1.82 ratio. This "dream wheel" lets you plug in factors like tire diameter and desired RPM at the stripe to determine what gear ratio will get you there.
