The Chevrolet Stovebolt engine is a straight-six engine made in two versions between 1929 and 1962 by the Chevrolet Division of General Motors.It replaced the company's 171-cubic-inch (2.8 L) inline-four as their sole engine offering from 1929 through 1954, and was the company's base engine starting in 1955 when it added the small block V8 to the lineup.
From 1954 to 1974, the small-block engine was known as the "Turbo-Fire" or "High Torque" V8. However, it was the 350 cu in (5.7 L) series that became the best-known Chevrolet small-block. Installed in everything from station wagons and sports cars to commercial vehicles, boats, industrial equipment, and even (in highly modified form) in ...
Also like the small block V8 engines, the 200 cu in (3.3 L) V6 used 2.45-inch (62.2 mm) main bearings and 2.1-inch (53.3 mm) rod bearing diameters. Being a 90° V6, Chevrolet took steps to eliminate the rough running tendencies of the 200. The crankshaft has each of its connecting rod throws offset by 18 degrees for each pair of rods. This ...
The Chevrolet small-block engine refers to one of the several gasoline-powered vehicle engines manufactured by General Motors. These include: The first or second generation of non-LS Chevrolet small-block engines; The third, fourth, or fifth generation of LS-based GM engines; The Chevrolet Gemini small-block engine
Chevrolet small-block V8s; GM Vortec 4300 90° V6; GM Iron Duke RWD inline 4 (early RWD Variants, later versions may use a FWD pattern, and have two possible starter locations) Jeep with GM Iron Duke inline 4 2.5L/151 in 3 (1980-1983). These use a Chrysler custom Torqueflite 904 automatic transmission with an integral Chevrolet bellhousing.
The lower half of the main bearings are typically held in place by 'bearing caps' which are secured to the engine block using bolts. The basic arrangement is for each bearing cap to have two bolts, but some engines may have four or six bolts per bearing cap (often referred to as "four-bolt mains" or "six-bolt mains" engines).
Identification between the two can be made by examining the hub: the protrusion of the hub through the center of the wheel denotes the preferred 10.5-inch full-floating rear axle. While the 9.5-inch rear end exhibits its own durability, it is generally considered less favorable for high-torque applications.
A cross-bolted bearing is a bearing, usually a crankshaft main bearing of a piston engine, reinforced with additional transverse bolts.Most bearing caps are retained by two bolts, one on each side of the bearing journal, and parallel to the cylinder axis (or, on vee engines, parallel to an axis bisecting the vee angle).
