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 4.4 L; 267.8 cu in (4,389 cc) engine had the 350's crankshaft stroke of 3.48 in (88.4 mm) and the smallest bore of any small-block, 3.5 in (88.9 mm), shared with the 200 V6 introduced a year earlier. It was only available with a M2ME Rochester Dualjet 210–effectively a Rochester Quadrajet with no rear barrels.
A fundamental specification for such engines, it can be measured in two different ways. The simpler way is the static compression ratio: in a reciprocating engine, this is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to that volume when the piston is at the top of its stroke.

Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
The 292 Chevrolet I6 is also undersquare, with a bore and stroke of 98.4 mm × 104.8 mm (3.875 in × 4.125 in) in (bore/stroke ratio = 0.939:1). Mitsubishi's 4G63T engine found primarily in many generations of Mitsubishi Lancer Evolution is an undersquare engine with a bore and stroke of 85 mm × 88 mm (3.3 in × 3.5 in).
The induction stroke is the first phase in a four-stroke (e.g. Otto cycle or Diesel cycle) engine.It involves the downward movement of the piston, creating a partial vacuum that draws an air-fuel mixture (or air alone, in the case of a direct injection engine) into the combustion chamber.
The first second-generation Oldsmobile V8 330 cu in (5.4 L) "Jetfire Rocket" introduced in 1964 and produced through 1967. It was released one year earlier than the tall deck 425, and debuted the standard 3.385 in (86.0 mm) stroke; bore was 3.938 in (100.0 mm). 330s were painted gold and had forged steel crankshafts.
The first example was the 1955 DKW 350. [1] The 1968 Suzuki RP68 was intended to compete in the 1968 season, however a rule change mandating single-cylinder engines meant that the 50 cc (3.1 cu in) RP68 never raced. [2] [3] Honda later revived the layout for the 1982–1984 NS500/NSR500 Grand Prix racing motorcycles. [4]
