Chevy 350 Identification
Manufactured from 1967 to 1998, the 350 c.i.d. engine became Chevrolets main eight cylinder small-block after it retired the earlier 283 and 327 engines. Long respected for its performance, reliability and interchangeability, the Chevy 350 is very common and easily identified.
General
One of the most popular Chevrolet engines ever produced, the 350 was used in everything from Corvettes to school buses. Standard Chevy identification techniques may be used to identify the engine, such as the orange paint and GM markings, but only the casting number gives exact identification.
Block Identification
To identify positively a Chevrolet 350 or any Chevrolet small-block, the engine casting number must be located and checked against a code chart. Chevrolet small-block casting numbers are located on the passenger side of the engine block on a machined pad in front of the cylinder head. The numbers often are hidden by the alternator.
Casting Codes
The casting numbers are a combination of numbers and letters, eight digits long. They give manufacture date and location in the pix, and the suffix, a series of three letters, gives the engine specifics. For example, casting code V0101CML reveals the suffix as CML. When matched to a chart, the code will reveal that the engine was a 350 built for a 1975 Camaro with 155 horsepower.
