As you are probably aware the release of the 265 cid engine in 1955 introduced a revolutionary engine design that has become one of the most, if not the most, popular overhead valve V8 engines ever manufactured. Often referred to as a "small block" or "mouse motor" due to its design and not necessarily its cubic-inch displacement possibilities. The 348 cid and 409 cid engines used from 1958 through early 1965 essentially truck engines and are often referred to as "w-engines" due to their unique cylinder head configuration. When General Motors introduced the Mark-IV 396 engine in mid- 1965 it was referred to as a "big block" or "rat motor."

The venerable small block engine has ranged in cubic-inch size from 262 to 400 in factory form until its demise in 2003, an impressive 48 year run, in favor of a new generation of small block V8s. Factory horsepower ratings ranged from 110 horsepower with the 262 V8 engine to a whopping 370 horsepower with the LT1 Corvette in 1970 before horsepower ratings were drastically cut in 1971 due to government emissions requirements.

Fuel systems included 2-barrel carburetor versions, 4-barrel carburetor versions, 2x4-barrel carburetor versions, and fuel injection.
