The 1973 LS-4 produced 275 hp (205 kW) and 468 lb⋅ft (635 N⋅m), with 5 hp (4 kW) and 10 lb⋅ft (14 N⋅m) gone the following year. Vortec 8100s were built at GM's Tonawanda Engine plant. Unfortunately, the raised deck design complicated the use of the block in racing applications, as standard intake manifolds required spacers for proper fit.

In all, over 90,000,000 small-blocks have been built in carbureted and fuel injected forms since 1955. 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. Another classic combo, here is the Chevrolet big block V8 engine set up with 2 four-barrel Holleys atop an early GMC blower. 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). It had slightly reduced power compared to the L29 454 and used a different PCM. Period magazine tests of the ZL1 were quite rare due to the rarity of the engine itself. A 409 hp (305 kW) version of this engine was also available, developing 1 hp per cubic inch with a dual four-barrel aluminium intake manifold and two Carter AFB carburetors. [29] Another version of the same engine is available as a high compression variant, codenamed ZZ572/720R Deluxe, generating a minimum of 720 hp (537 kW) on high-octane, i.e., race-gas.[30]. The big block LS6 was manufactured from 1970 to 1976 in several General Motors products, including the Chevrolet Caprice, Chevelle, Corvette, El Camino, and Monte Carlo as well as the GMC Sprint. 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.

The 502—with a 501.28 cu in (8.2 L) total displacement—had a bore and stroke of 4.466 in × 4 in (113.4 mm × 101.6 mm) and a cast iron 4-bolt main block. Same as 396 cu in (6.5 L) L-34. LS-1: produced 1969, 10.25:1 compression, Q-jet carburetor, oval port closed chamber heads, hydraulic lifters, nodular iron crankshaft, and two-bolt main caps. Gone was the chamber-in-block design of the W-series engine (which caused the power curve to drastically dip above 6500 rpm), and in its place was a more conventional wedge chamber in the cylinder head, which was now attached to a conventional 90 degree deck. 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! Several LS-7 intake manifolds were individually produced and sold to the general public by a few Chevrolet dealers as optional performance parts. Distributors with adjustable collars that allowed adjustments to the length of the distributor shaft also had to be used with 366 and 427 truck blocks. As American automobiles grew in size and weight following the Second World War, the engines powering them had to keep pace. It was designed from a "clean sheet of paper" like the 1955 265 small-block was and it … The LS-7 was later offered as a crate engine from Chevrolet Performance with an officially rated power minimum of 500 hp (373 kW) Gross. L88 was rated for 430 hp (321 kW) at 5200 rpm. 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. Although all of Chevrolet’s siblings of the period (Buick, Cadillac, Oldsmobile, and Pontiac) designed their own V8s, it was the Chevrolet 350 cu in (5.7 L) small-block that became the GM corporate standard.

Bore and stroke was 4 1⁄8 in × 3 1⁄4 in (104.8 mm × 82.6 mm), resulting in a substantially oversquare design. This engine had an overhead valve design with offset valves and uniquely scalloped rocker covers, giving it a distinctive appearance. The W-series was produced from 1958 to 1965, and had three displacement options: The W-series engine was made of cast iron.

"The big block Chevy is one of the most raced engine platforms in motorsports. While this option produced no power advantage, it did reduce engine (and hence, vehicle) weight by roughly 75 pounds (34 kg). The theory behind this sort of arrangement is that maximum brake mean effective pressure (BMEP) is developed at relatively low engine speeds, resulting in an engine with a broad torque curve. Mark IV engines also found themselves widely used in power boats. Chevrolet had introduced its popular small block V8 in 1955, but needed something larger to power its medium duty trucks and the heavier cars that were on the drawing board. Over the years, every American General Motors division, except Saturn, used it and its descendants in their vehicles.

However, most of these items were racing parts originally designed for Can-Am competition that found their way onto dealers' shelves, and were meant to boost the engine's power output. With stock exhaust manifolds and operation in the 6,800 rpm range, it was generally accepted that the engine was capable of producing in excess of 500 hp (373 kW) gross with free-flowing (open) long tube headers. Due to the new spark plug angle, the clearance provided by the distinctive scalloped valve covers of the W-series was no longer needed, and wide, rectangular covers were used. [24] Structural changes were carried out to the cylinder case to improve the integrity of the bores and the inlet manifold was changed to a single-piece design.

Owing to the appearance of the compound angularity of the valves,[9] the automotive press dubbed the engine the "porcupine" design. Due to the relatively low mass of the valve train, mechanical lifter versions of the W-series engine were capable of operating at speeds well beyond 6000 RPM.

Its design shared much with the L29 454, but with the addition of forged pistons and crankshaft, and coil near plug ignition. L88 had a 12.5:1 compression ratio with closed chamber heads except during the last half of 1969, when it had open chambered heads that yielded 12.0:1.

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. Mechanical lifters and triple two-barrel carburetors brought the "Special Super Turbo-Thrust" up to 315 hp (235 kW). Like its predecessor, the Mark IV used crowned pistons, which were castings for conventional models and impact extruded (forged), solid skirt types in high performance applications. The engine family from which all Chevy V8s from the big blocks to today's LS7 and LS9 evolved is the 265/283 small block family.
