International delivery.The Chevrolet "Big Block" is a term for a series of large displacement V8 engines that have been developed and produced in the United States from the s until As American automobiles grew in size and weight following the Second World Warthe engines powering them had to keep pace.

Chevrolet had introduced its popular small block V8 inbut needed something larger to power its medium duty trucks and the heavier cars that were on the drawing board. The first version of the "Big Block" V8 Chevrolet engine, known as the W-series, was introduced in Chevrolet designed this engine for use in passenger cars and light trucks.

This engine had an overhead valve design with offset valves and uniquely scalloped rocker coversgiving it a distinctive appearance. The W-series was produced from toand had three displacement options:. The W-series engine was made of cast iron.

The engine block had 4. Heads used on the high performance and engines had larger ports and valves than those used on the and the base passenger car and truck engines, but externally were identical to the standard units. No satisfactory explanation was ever offered for why this change was made. However, it did provide a fairly reliable way to differentiate between the smaller and larger versions of the engine. The push rods also acted as conduits for oil flow to the valve gear. 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 RPM.

The combustion chamber of the W-series engine was in the upper part of the cylindernot the head, the head having only tiny recesses for the valves.


This arrangement was achieved by combining a cylinder head deck that was not perpendicular to the bore with a crowned pistonwhich was a novel concept in American production engines of the day.

As the piston approached top dead centerthe angle of the crown combined with that of the head deck to form a wedge-shaped combustion chamber with a pronounced quench area. The spark plugs were inserted vertically into the quench area, which helped to produce a rapidly moving flame front for more complete combustion. 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.

With its relatively flat torque characteristics, the "W" engine was well-suited to propelling both the trucks and heavier cars that were in vogue in the US at the time. The W-series was a physically massive engine when compared to the "Small Block" Chevrolet engine. The first iteration of the W-series engine was the "Turbo-Thrust" cubic-inch 5.Miscellaneous 0 comments.

InChevy converted to a long water pump that demands different pulleys and accessory drive mounts. The most typical long water-pump setup mounts the alternator on the passenger side. This comparison of the long water pump left versus the short water pump right reveals the height difference. The long water-pump reference height is 7 inches. The biggest hassle with aftermarket pumps, pulleys, and brackets is that this reference height can vary dramatically.

This is often what causes pulley misalignment. However, inexpensive iron rebuilt pumps you get from the local auto parts store are often way off. The best way to align all your pulleys is to use a quality pump. Gasket, Canton Racing, and others sell these aluminum water-pump and crank-pulley shims that will space out either pulley to create the proper alignment.

You could also make your own. You cannot interchange short and long water-pump pulleys without causing all kinds of headaches for yourself. This requires using a header mount for the alternator. Unfortunately, those standard alternator mounts are very flimsy and often break.

Tim can also mount the alternator on the passenger side as well. This is a shot of a typical serpentine belt-drive setup on a late-model TPI Camaro engine that requires the use of a reverse-rotation water pump because of the belt routing. The Corvette accessory-drive layout is different, but still requires the use of a reverse-rotation water pump. This would require moving your alternator charging wiring, however. An interesting option is to use a Chevy truck bracket that uses accessory bolt holes in the cylinder heads to mount the alternator in close to the long water pump.

March Performance makes several examples of serpentine belt drives for a standard-rotation long water-pump setup both with This is a most confusing story about perhaps one of the simplest systems on an engine. This story will outline the three basic systems that Chevrolet has used to drive the pumps, belts, and pulleys throughout the most popular 35 years of the small-block.

Complete combustion of the fuel would be ideal, however, given the inefficiency of the engine, this is very difficult.

Timing is adjusted to maximize the fuel burn as much as possible. Fuel takes a certain amount of time to burn.

As the engine rpm increases the time the fuel remains in the engine decreases exponentially, thus ignition timing is advanced to allow more time for combustion.

Mark the timing mark on the harmonic balancer with the white marker to make it more visible for the timing light. Look for the long straight line on the balancer and mark this. Look at the timing plate on the driver's side of the timing chain cover. Notice that it has a V cut in the center of the marker plate -- this is top dead center on the compression stroke.

The numbers to the left of the V, looking at the engine from the front, are degrees of advance or how many degrees before top dead center.

The numbers to the right of the V are degrees after top dead center. You always want to have the timing advanced or before top dead center. Connect the timing light by connecting the black lead to the negative battery posts and red lead to the positive battery post. Lay the wires across the top of the radiator or intake manifold so they don't get caught in the fan.

Connect the carbon connector probe to the number 1 cylinder spark plug wire by pressing on the connector handle and placing the jaws over the wire and allowing the jaws to close. Disconnect the vacuum advance hose on the distributor and plug the hose with a screw. Start the engine. Shine the timing light at the harmonic balancer timing mark on the driver's side of the engine. Read the number on the timing plate adjacent to the timing mark on the balancer.

The initial timing should be 4 degrees before top dead center BTDC. If the mark is adjacent to a higher number BTDC, the distributor must be rotated clockwise to bring it down to 4 degrees.

If the number is lower or after top dead center ATDCturn the distributor counterclockwise. Turn the engine off. Loosen the distributor hold down clamp using a wrench.

Start the engine and rotate the distributor as outlined previously. Walk around to the driver's side and check the timing to see if you moved the distributor enough to place the timing mark on the 4-degree mark BTDC.

Keep adjusting the distributor until 4 degrees before top dead center BTDC is achieved. Tighten the distributor hold down bolt using the distributor wrench. Pull the screw out of the vacuum advance hose and reconnect the hose to the distributor.

Take us with you! We are proud to announce that SerpentineBeltDiagrams. Serpentine Belt The serpentine belt was first introduced in by Mercedes. The serpentine belt was designed to replace the multi belt drive belt systems and control multiple components on your engine with a single belt.

The single belt is more efficient, easy to change and has a longer life span than the multiple belt systems used in earlier model vehicles. Tensioner The use of a serpentine belt requires a belt tensioner or idler pulley to apply the necessary tension to the belt. The use of a tensioner pulley or idler pulley also makes changing your belt a lot faster and easier than multi belt systems.
