The small-block family line was honored as one of the 10 Best Engines of the 20th Century by the automotive magazine Ward’s AutoWorld. The 283, famous for being one of the first engines to make 1 hp per cubic inch is also famous for being the evolutionary stepping stone that would give rise to later small blocks and to the “W” blocks which would later give rise to the … The push rods also acted as conduits for oil flow to the valve gear. For 1991 General Motors made significant changes to the Big-Block resulting in the Generation V. The block received a one-piece rear seal and all blocks received 4-bolt mains. "The big block Chevy is one of the most raced engine platforms in motorsports. However, it did provide a fairly reliable way to differentiate between the smaller and larger versions of the engine. A torque-monster Chevrolet big-block with simple bolt-ons can make 550 lb-ft of torque with a yawn, and they do it with low-octane fuel! Owing to the appearance of the compound angularity of the valves,[9] the automotive press dubbed the engine the "porcupine" design. Other important differences between the Vortec 8100 and older Big Blocks include a changed firing order (1-8-7-2-6-5-4-3), a new 18-bolt head bolt pattern, longer connecting rods, different symmetrical intake ports, different oil pan rails and the use of metric threads throughout the engine.

Heads used on the high performance 409 and 427 engines had larger ports and valves than those used on the 348 and the base 409 passenger car and truck engines, but externally were identical to the standard units. The fuel-injection system for the Vortec 8100 is nearly identical to that used on Gen III engines, right down to the fuel and spark tables in the ECU.[31]. Aside from the new cylinder head design and the reversion to a conventional 90 degree cylinder head deck angle, the Mark IV shared many dimensional and mechanical design features with the W-series engine. Several LS-7 intake manifolds were individually produced and sold to the general public by a few Chevrolet dealers as optional performance parts. Chevrolet had introduced its popular small-block V8 in 1955, but needed something larger to power the medium-duty trucks and its heavier cars that were on the drawing board.

Mark IV engines saw extensive application in Chevrolet and GMC medium duty trucks, as well as in Blue Bird Corporation's All American and TC/2000 transit buses (the latter up until 1995, using a 427 with purpose-built carburetor). Unfortunately, there is no evidence from GM that shows 57 cars were built. When the Chevrolet Mark IV big-block V8, a more modern and efficient package, became available in heavy-duty truck versions of 366 CID and 427 CID, that was the end of the line for the 637 gasoline V8, and the 1,200 lb brute was discontinued for good in 1972. In 1972, only the LS-5 remained, when SAE net power ratings and the move towards emission compliance resulted in a temporary output decline, due to lowered compression, to about 270 hp (201 kW) and 468 lb⋅ft (635 N⋅m). Although introduced as the Vortec 7400 in 1996, it was basically a 454 Big-Block with a hydraulic roller cam, parts more suitable for use in light duty trucks, and more advanced technology. 2/11 The Mark IV 396ci V-8 was introduced in … The valves continued to use the displaced arrangement of the W-series engine, but were also inclined so that they would open away from the combustion chamber and cylinder walls, a design feature made possible by Chevrolet's stud mounted rocker arms.
