The 400 is the only engine that uses a 2.65 in (67.3 mm) main bearing journal and a 2.1 in (53.3 mm) rod bearing journal. The connecting rod was also 400 specific being 5.565 in (141.4 mm) as opposed to the 5.7 in (144.8 mm) rod used in all other small-block Chevrolet engines.
Within 18 months, the design of the Chevy II was completed, including new 153 cu in (2,512 cc) four-cylinder and 194 cu in (3,185 cc) six-cylinder engines to power it. The 153 cu in engine had a 3 + 7 ⁄ 8 -inch (98 mm) bore and 3 + 1 ⁄ 4 -inch (82.6 mm) stroke, with two overhead valves per cylinder actuated by pushrods and a 1-3-4-2 firing ...
The powerplant used in Saturn S-Series automobiles was a straight-4 aluminum piston engine produced by Saturn, a subsidiary of General Motors. The engine was only used in the Saturn S-series line of vehicles (SL, SC, SW) from 1991 through 2002. It was available in chain-driven SOHC or DOHC variants.
The only parts carried over from the 1978 engines were the connecting rods. [5] Peak power increased to 90 hp. For 1980 the Iron Duke engine was redesigned to be mounted transversely, to suit the new front-drive General Motors "X-body" cars. The bellhousing bolt pattern was revised to match that of the new 60° V6 engine.
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
Connecting rods don't just fail. They're just the obvious sign that something went wrong. I've only ever heard of connecting rod failures where they were defective, such as in the early 80's Chevy 2.5L "Iron Duke" 4-cylinder, and in cases where extreme cylinder pressure overcomes the strong of the rod... i.e. when someone has tried to make more ...
The GMC straight-6 engine was a series of gasoline-powered straight-six engines introduced in the 1939 model year by the GMC Trucks division of General Motors.Prior to the introduction of this new engine design GMC trucks had been powered by straight-six engines designed by the Buick, Pontiac and Oldsmobile divisions of GM.

Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. [4] The connecting rod is required to transmit the compressive and tensile forces from ...
