Although the high-performance 429 Cobra Jets were still rated at the same power as the 1970 models, Super Stock and Drag Illustrated had disappointing results from its test of a 1971 Torino Cobra. They tested a Cobra equipped with the 370 hp (280 kW), 429 CJ, C-6 automatic, 3.50:1 gears, and were only able to turn a best quarter-mile time of ...
1970 Ford Torino with 429 Super Cobra Jet, showing shaker scoop and intake. The Super Cobra Jet (429SCJ) was fitted with a Holley 780 cu ft/min (22 m 3 /min) Vac-Secondaries square-bore 4-bbl carburetor, larger mechanical camshaft, a four-bolt main block, forged pistons, single valve relief, [4] forged rods, and Brinell tested cast iron crankshaft.
After the 1970 season, NASCAR effectively banned the "aero cars" by restricting all five of these "production" cars to having to compete with engines no larger than 305 cubic inches of displacement (vs. the 426, 427, & 429 cubic inches other cars could use), and the competitive history of the Talladega (and its aerodynamically developed rivals ...
While Chevrolet's El Camino used the same body from 1968 to 1972, 1970 had a complete restyle for the Ranchero, which had started with a boxy body style. Both the Torino and Ranchero featured a shallow-pointed grille and front end with smooth, somewhat more curvaceous lines influenced by coke bottle styling. A fourth trim option was made ...
The engine was rated at 266 hp (198 kW) (SAE net) for 1972 when installed in the Mustang, and 248 hp (185 kW) in the Torino and Montego. [5] An increase in the combustion chamber size and the use of smaller valves occurred in 1973, [ 1 ] which reduced horsepower to 246 hp (183 kW) for the four-barrel for the intermediate Fords, though it still ...
After the 1970 season, NASCAR effectively banned the "aero cars", by restricting all four of the limited aero "production" cars to having to compete with engines no larger than 305 cubic inches of displacement (vs. the 426, 427, & 429 inches that the other cars could run), and the competitive history of the Mercury Cyclone Spoiler II (and its ...
The 390 was offered solely as a 320 hp four-barrel. The 428 Cobra Jet was the largest Cougar engine, rated at 335 hp (with or without Ram Air). [12] As a mid-year change, Mercury introduced the Boss 302 V8 on April 1, 1969, in conjunction with the introduction of the Cougar Eliminator (with the Boss 302 engine being exclusive to the Eliminator).
The addition of emissions controls and the adoption of unleaded fuel required lowered compression ratios and retarded ignition timing. In one example, the range-topping 429 V8 would see its output drop from 365 hp to 212 hp from 1971 to 1972. In 1972, the 429 was joined by a 224-hp 460 cubic-inch V8 seen previously in the Lincoln lineup. [32]
