This package consists of a high-compression 400-cubic-inch with a 2-barrel carburetor and special cam that moves the torque peak to a lower rpm than normal driving through a 2.41 rear axle. Also included is something particularly delightful, we think: the 4-4-2 suspension and chassis. A car this equipped can be correctly considered a 4-4-2 (less identification) with a different gine and final drive ratio."242"Oldsmobile's GM's first "gas saving" car and in 1967 six years before the 1973 oil crisis. Wow GM 43 years later and you still don't have anything even remotely as revolutionnairy.Here are precise mpg figures measured on the GM Proving Grounds with fuel meter and fifth wheel, running at constant speeds in 40� weather-30 mph, 23.15 mpg; 40 mph, 23.65 mpg; 50 mph, 21.04 mpg 60 mph, 19.26 mpg; 70 mph, 17.22 mpg; 80 mph, 15.26 mpg; and 90 mph, 13.18 mpg.Although the 4-4-2 had the standardfor-automatic 3.08 rear axle, a fairly high-speed ratio, its engine sounded comparatively busy upon switching from the TC car with the 2.41 axle. At 65 mph the TC engine is churning over at a relaxed 2200 rpm while the 4-4-2 cranks out nearly 3000 at the same speed. Without hesitation we rate the TC-packaged car above the 4-4-2 as an allaround road car for this reason. This goes for all kinds of roads -not just turnpikes - because with an identical suspension, it gives away nothing to the 4-4-2 in this department.
