Absolutely! As for describing it, I'll take the easy way out, and steal a section from Wikipedia:
"It shared sheet metal with the Oldsmobile F-85, the first-generation Tempest had several features that differentiated it from the other compact GM cars. The engine was a 195 cubic inch (3.2 L) straight-4
marketed as the "Trophy 4
," derived from the right cylinder bank of Pontiac's 389 cubic inch "Trophy 8" V8 engine
The Tempest featured a drivetrain with a rear-mounted transaxle
that was coupled to a torque shaft arcing in a 3 in (76 mm) downward bow within a curved, longitudinal tunnel. Use of the torque shaft was the result of being forced to use the Corvair floorpan which, being a rear engine platform, had no drive shaft.
To combine flexibility with strength in the proper proportion, the shaft was forged of SAE 8660 steel (high nickel, chrome and molybdenum
alloying percentages) for torsion bar specifications. For automatic cars, the shaft was 0.65 in (17 mm) in diameter and 87.25 in (2.216 m) long, while the manual-box shaft was 0.75 in (19 mm) by 82 in (2.1 m). This joined the forward engine and the rear transaxle (therefore no transmission hump) into a single unit, helping to reduce vibration.
The design, known as "rope drive," had only been seen previously on General Motors' 1951 Le Sabre concept car
A number of years ago, I was with a buddy at the large, local automotive swap meet that happens twice a year. A friend of his came up and announced that he had just come from the "Car Corral", where he had bought the '63 Tempest with the 326 in it. I mentioned the "flexible driveshaft" and the transaxle set-up, and he looked at me like I was crazy. We walked over to the car, and I showed him. He was both intrigued, and concerned, as he should be. Parts for them are not that easy to come by, and repairing the unique drivetrain can be challenging. Hell, even the engine block is unique to the set-up, as the bellhousing mounting points are shared with no other Pontiac. Who'd a thunk it?
