First introduced in , the family is a continuation of the earlier first- and second-generation Chevrolet small-block engine , of which over million have been produced altogether, [5] and is also considered to be one of the most popular V8 engines ever. A clean-sheet design, the only shared components between the Gen III engines and the first two generations of the Chevrolet small-block engine are the connecting rod bearings and valve lifters. The brainchild of Chevrolet chief engineer Ed Cole , the first generation of the Chevrolet small-block engine was first unveiled in the Chevrolet Corvette and Chevrolet Bel Air , both powered by the cu in 4, cc "Turbo-Fire. Nicknamed the "Mighty Mouse," the Turbo-Fire soon became popular within the hot rodding community too, along with scoring wins in stock car racing. General Motors would produce more powerful and larger displacement iterations of the small-block, until the advent of stringent emission regulations in the late s severely limited performance. It featured reverse-flow cylinder heads , a new ignition system , and new engine block, but the valvetrain and engine mounts were carried over in order to maintain a degree of compatibility with the previous generation. Other modifications such as a better flowing intake manifold and cylinder heads gave the LT1 a power output of hp kW; PS. The decision to stick with pushrod technology was seen as archaic at the time; such engines were seen as outmoded compared to the smaller capacity but more powerful and fuel efficient overhead cam engines favored by European and Asian manufacturers. One of GM's domestic rivals, Ford , had announced plans to axe its small block engine from production in the early s, [31] in favor of its Modular engines, while the other domestic rival, Chrysler Corporation, had stopped building passenger cars with V8 engines years prior, relegating them to its trucks and SUVs. Many car enthusiasts also wanted a dual overhead cam engine; [26] GM had developed the Northstar engines for Cadillac, but those engines were initially exclusive to that brand and not originally designed for rear-wheel-drive vehicles. Later on, Sam Winegarden, former General Motors chief engineer for small-blocks, stated that despite the stigma of the pushrod engine being "a symbol of the uncompetitiveness [sic] of the domestic industry," the decision to stick with pushrods was made on the basis that switching to overhead camshafts was unnecessary; the power requirements for the Corvette were satisfied by simply increasing engine displacement. Approval for the Gen III was granted in May , after a seat-of-the-pants decision made by General Motors executives who went for a drive in two Corvettes—one equipped with a traditional pushrod engine and one with an avant-garde dual overhead camshaft engine. Tom Stephens, then—executive director of General Motors Powertrains, was the man in charge of the project.

The 4. These engines are strong and durable. Many people use them with boost or nitrous. With upgraded internals, the blocks can handle over 1, hp. These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.
