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.

Rather motor 4.8 chevrolet allow a "high-strung" small-block to fail the heavy-duty truck market, the iron block, lack of both stop-start and cylinder deactivation, longer stroke and rod ratio, lower compression, lesser 87 Octane requirement, and greater displacement all suggest that the L8T was designed specifically to assuage the heavy-duty truck market's concerns. Ryan came through when all else failed.
