1957 Chevrolet Engines – The really hot news about the “Sweet, Smooth and Sassy” 1957 Chevrolet was the 283 cubic inch V-8. The extra horsepower came from increasing the bore to 3.875 inches, the stroke remained the same at 3.00 inches. The new V-8 packed more power than the hottest 1956 Chevrolet setup.

The ’57 Chevy’s popularity stemmed from the performance of the newly enlarged 283 cubic inch V-8 with “Ramjet Fuel Injection”. The Ramjet fuel injection was an option on all twenty 1957 Chevrolet models and standard on the corvette. Chevrolet now claimed one horsepower per cubic inch and this was first for Chevrolet!

The 283 cubic inch V-8 was available in 6 versions, 2 with fuel injections and 4 with carburetors. Increasing engine choices from five in 1956 to eight in 1957. The familiar two barrel, 162 horsepower 265 cubic inch continued as the base V-8 with manual transmission. The 283 cubic inch V-8 was available with a two barrel carburetor, four barrel carburetor, two 4 barrel carburetors and fuel injection. These combinations on the 283 cubic inch V-8, carburetors and fuel injection plus three speed manual transmission, Powerglide and a new Turboglide automatic transmission produced 162 horsepower to 283 horsepower.

Regardless of the power rating, all 1957 Chevrolet Engines featured a number of internal changes. Fuel passages and exhaust manifolds ports were tapered, castings were thicker, new fuel filters, wider main bearings, stainless steel expander for piston oil control rings and the choke was relocated to improve hot starting. Updated electrical items included relocating the battery and voltage regulator, multi-plugs on the electrical wiring and a new distributor.

The manual three speed transmission remained the basic transmission on the ’57 Chevrolet, with overdrive as an option since 1955. Also available on both the Blue Flame six cylinder and V-8’s was the Powergide that had been around for several years. On the bigger V-8, the new Turboglide was an option. Mechanically, the Turboglide consists of three turbines and two planetary gear sets, combined with a variable pitch stator and conventional torque converter pump, all enclosed in a die cast aluminum housing that was 82 pounds lighter than a Powerglide. One early performance test of a 270 horsepower 283 cubic inch V-8 with two 4 barrel carburetors went from a standing start to 45 mph in 6.75 seconds, 60 mph in 9.9 seconds and in the quarter mile 17.5 seconds at 77.5 mph.
