Chevy Truck (1955-1959)
Introduced in March of 1955, Chevrolet's new 'Task Force' series of trucks was quite a departure from their existing line of pickups. Smooth, rounded sheet-metal replaced the old pontoon-style fenders, and large, wrap-around windshield glass offered better visibility and gave a more contemporary look. And for the first time, an eight-cylinder motor was available under the hood.
1955 Chevy Pickup
The 1955 model year began with the continuation of Chevrolet's Advance Design pickups, which dated back to 1947. These first-series trucks, built until March of 1955, were durable and sold well. But Ford's new 1953 F100 pickup, as well as Dodge's new model in 1954, prompted a re-design to a more modern looking truck. Taking styling cues from their successful passenger car platform, Chevy's second-series pickups were re-engineered and restyled for mid '55.
Task Force trucks rode on a new, wider six-cross member frame, allowing longer front and rear leaf springs to be fitted. The standard half-ton 3100 series had a 114" wheelbase, which it shared with the smooth-sided 3124 series Cameo Carrier. The 3200 series trucks had a longer bed and rode on a 123" wheelbase. Three-quarter ton models used 3500 and 3700 designations. Chevy's venerable 'Stovebolt' Six, standard on all models, displaced 235-cid and produced 123-horsepower.

Electrical systems, upgraded from 6 to 12 volts, were one of many improvements on the new series of trucks. The biggest news was Chevrolet's new small-block V-8 engine, introduced on 1955 passenger car models, was now offered with their trucks. More efficient and more powerful than the six-cylinder motor, the 265-cid V-8 was also 30 pounds lighter. 1955 Chevy V-8's did not have an oil filter nor a provision for one. An add-on filter canister, mounted atop the thermostat housing, was optional.
1956 Chevy Pickup
Aside from slight emblem changes, 1956 Chevy truck exteriors were unchanged. The long options list from last year was back, including power steering, power brakes, whitewall tires, full wheel covers, chrome front and rear bumpers, and a factory-installed radio. The Custom Cab option included chrome interior door knobs, arm rests, dual-sun visors, a cigarette lighter, and a large wrap-around rear window. All V-8 blocks were now machined with an oil filter boss, allowing a full-flow oil system.
1957 Chevy Pickup
Third-year Task Force pickups received a distinctive new grille that would be a one-year feature only. Increasing the bore of the small-block V-8 brought displacement up to 283-cid. Horsepower increased to 185-horsepower. Five transmissions were available: three-speed, heavy-duty three-speed, three-speed with overdrive, four-speed, or GM's Hydra-matic automatic.
1958 Chevy Pickup
Styling on all Chevy passenger car and truck models were changed to accommodate the industry-wide switch from two to four headlamps. The new Apache model came standard with painted grille and front bumper, and could be upgraded to chrome. The new Fleetside model featured a smooth-sided cargo box and larger bed capacity. Model designations were shortened to 31, 32, 35 and 38 series. A recasting of the 283 small-block gave thicker cylinder walls and side motor-mount bosses.
Before 1958, Chevrolet had used outside suppliers such as Minnesota-based NAPCO (Northwestern Auto Parts Company) to convert their light and medium-duty trucks to four-wheel-drive. A GM-designed 4X4 drivetrain was now available. Air-conditioning also became available as a dealer-installed, factory-authorized option.
1959 Chevy Pickup
The last year of the Task Force line saw minor changes. Front and side emblems were changed to distinguish this year's model from last year's. Posi-traction became an option, and larger drum brakes were used. In all, 13 different truck models were available this year.

Generator To Alternator Conversion
If you're thinking of converting from 6-volts to 12-volts, check out the PowerMaster 82051 alternator. You get the traditional look of a generator, but it's actually a 12-volt, negative-ground alternator that produces 65 amps at idle and 90 amps going down the road.
