Small-Block Family

The 327-cubic-inch engine was among nine small-block V8s produced by General Motors that included the smallest--262 cubic inches--up to the 350 and 400, according to novak-adapt.com.

Specifications

The 327 generated anywhere from 250 to 375 horsepower with a 4-inch bore and 3 1/4-inch stroke, according to novak-adapt.com.

Performance Option

Musclecarclub.com reports that many 1960s Chevy cars were equipped with the 262 or 283 V8s, but the 327 was offered as a performance option, which was popular in the El Caminos.

Carburetor vs. Fuel Injection

The 327 could be fueled either by a Carter four-barrel carburetor, which could produce up to 340 hp, or the Rochester mechanical fuel injection system capable of producing up to 375 hp.

Corvette

The 327 was standard equipment in the second-generation 1963 to 1967 fuel-injected Corvette Sting Ray that was matched with a three- or four-speed manual transmission or the Powerglide automatic.

AMC 327

Long before GM produced the 327, American Motors in 1957 debuted its 288-hp 327 for the Rambler Rebel. It originally was designed as a fuel-injection model, but early problems prompted AMC to switch to the carburetor, according to allpar.com.
