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. Non-toxic inks. 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. 150–254 hp (112–189 kW) Torque output. This resulted in superior vehicle weight distribution for improved handling, although the difference in straight line performance was negligible. 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). The cylinder block, although more substantial in all respects, used the same cylinder bore pitch (bore spacing) of 4.84 in (123 mm) with a larger 2.75 in (70 mm) main bearing dimension, increased from the 2.5 in (63.5 mm) of the older engine (in fact, the shorter-stroke 348 and 409 crankshafts could be installed with the use of "spacer bearings" without modifying the crankshaft). Blocks made of both iron and aluminium alloys, for many different purposes—e.g. 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. In all forms (except the ZL-1 Can-Am model), the "rat motor", as it was later nicknamed (small-block engine being a "mouse motor"), was slightly heavier than the W-series model, with a dry weight of about 685 lb (311 kg). Introduced in 1996, it was produced for five years, until replaced by the Vortec 8100. One minor difference between the 348 and 409/427 was the location of the engine oil dipstick: it was on the driver's side on the former and the passenger's side on the latter. (102 octane RON [Sunoco 260] represented the highest octane gasoline sold at common retail stations. 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. 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. While this option produced no power advantage, it did reduce engine (and hence, vehicle) weight by roughly 75 pounds (34 kg). The Vortec 7400 L29 7.4 L (454 cu in) V8 was a truck version of the Chevrolet Big-Block engine. For the Volkswagen Type 2 , 1972's most prominent change was a bigger engine compartment to fit the larger … This engine had an overhead valve design with offset valves and uniquely scalloped rocker covers, giving it a distinctive appearance. 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. On December 17, 1960, the 409 engine was announced along with the Impala SS (Super Sport) model. In addition, a 340 hp (254 kW) version of the 409 engine was available from 1963 to 1965, with a single 4-barrel cast iron intake mounting a Rochester 4GC square-bore carburetor, and a hydraulic-lifter camshaft.

Here is a great profile article on the late-great Bill “Grumpy” Jenkins and the 1967 big-block engines that made his Chevy drag cars so fast. The Mark IV differed from the W-series engine in the placement of the valves and the shape of the combustion chambers. It produced 265 hp (198 kW). This arrangement was achieved by combining a cylinder head deck that was not perpendicular to the bore with a crowned piston, which was a novel concept in American production engines of the day. Is natural bug repellant safe? Later blocks intended for performance use had the main oil gallery moved up to the cam bearing bore area and provided "priority main" oiling, improving the oil system even further. Chevy Big Block engines are a series of large displacement engines including: 348 ("W" series only) 366, 396, 402, 427, 454, 502 and, most recently, the 572. Additionally the main oil galley was moved from near the oil pan to near the camshaft. street-use, racing, etc.—are available in stock or modified configurations, as well as with increased deck height to allow for a longer stroke or more favorable rod length ratios, depending on intent, providing the ability to make engines with capacities of 632-cubic-inch (10.4 L),[33] 798-cubic-inch (13.1 L),[34] and as large as 1,005.8-cubic-inch (16.5 L).[35]. Racing-spec cam, high-flow aluminium heads (casting #s varied by model year) and some upgraded, competition-grade parts, Aluminium block with open chamber "3946074" aluminium heads (the early Corvette RPO engine featured a closed chamber head); cam even "hotter" than L88's; upgraded parts similar to L88's, L88-ZL1 hybrid; iron block with aluminium heads. It's time to use a bug repellant that 1.) No satisfactory explanation was ever offered for why this change was made. The push rods also acted as conduits for oil flow to the valve gear. The initial version of the engine produced 360 hp (268 kW) with a single 4-barrel Carter AFB carburetor. The Vortec 7400 L21 was a commercial version of the Chevrolet Big-Block engine used in the medium duty truck platform.
