The secret to that power, if it is a secret, is that the engine can inhale all the air-fuel mixture it needs. That is really the only avenue to performance these days, since the SD-455, like all those "performance" engines, must squeeze its power out of 91-octane fuel (which ...
Things were tough in ’74, especially for cars that weren’t moderate in their fuel consumption. The October ’73 oil embargo drove up fuel prices, created long lines at the pump, and brought us such gems as odd and even rationing. The result was a recession that started in ’74 and c...
The optional 455 had the same rated power (although at a peak of 3,600 rpm), but substantially more torque. Most of the drop was attributable to the new rating system (which now reflected an engine in as-installed condition with mufflers, accessories, and standard intake). The engines ...

Grow the Strato-Streak did — from 287 cubic inches (4,706 cc) in 1955 to 455 cu. in. (7,481 cc) in 1970. Over the years, it was offered in a bewildering number of states of tune. Fuel-injected, it had powered the first Bonneville, Bunkie Knudsen’s declaration of intent that ...
Higher-than-ever fuel prices were but one legacy of the 1973-74 Middle East oil embargo, though gas was becoming costlier well before that. Renewed buyer interest in thrifty compacts -- and Pontiac's lack of same -- prompted the division to put a different nose on Chevrolet's 111-inch-...
For 1972, only Net figures were to be given, so consumers could not even see the Gross ratings. So while the 1972 versions of 400 and 455 V8s were not substantially changed from the prior year, they had radically worse performance on paper. The 455 could still pump out a healthy 375 lb...
to the steering column. The seller states that the car is loaded with power windows, power locks, and air conditioning. However, the ad also states that the car needs to be completed. The number of needs is a short list including the fuel gauge, clock, radio, air conditioning, and ...
000. That momentum wouldn’t hold for long as the OPEC oil embargo caused gasoline prices to soar in 1973-75 and car buyers began moving to more fuel-efficient alternatives. Nonetheless, these were beautiful and popular machines at the time, including this well-used 1973 edition. Located in ...
