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.
It offers the airflow of more expensive heads, at a much lower cost. It does, however, require a specific intake manifold (the L31 has four bolts per head attaching the intake manifold, as opposed to the "traditional" six bolts per head found on older Chevrolet small-blocks). Chevrolet's L31 was replaced by GM's LS-based 5.3L LM7 and 6.0L LQ4.

MerCruiser sterndrives and inboards range from 135 to 430 horsepower (320 kW) and Mercury Racing outboards produce up to 450 horsepower (340 kW) and sterndrives to 1,750 horsepower (1,300 kW). Subsidiaries include Mercury Precision Parts and Accessories as well as Mercury propellers and Mercury Jet Drives.
Coolant is routed out of the block through the intake manifold. The design was soon bored to 260 cu in (4.3 L) and again to 289 cu in (4.7 L), then stroked to 302 cu in (4.9 L), settling on the most common displacement offered until the engine's retirement in 2001, nearly 40 years after the basic block design debuted.
An inlet manifold or intake manifold (in American English) is the part of an internal combustion engine that supplies the fuel/air mixture to the cylinders. [1] The word manifold comes from the Old English word manigfeald (from the Anglo-Saxon manig [many] and feald [repeatedly]) and refers to the multiplying of one (pipe) into many.
A torque-biased variant of the Coyote is produced as an alternative to the EcoBoost V6 in the F-150 pickup truck. The F-150 5.0 L receives a lower compression ratio (10.5:1), intake camshafts with less duration, cast iron exhaust manifolds, and revised cylinder heads to improve cooling. The intake manifold changed only in color, and height.
Several significant changes were made in 1987, which included: an improved cylinder head, intake manifold, and throttle-body fuel injection module; a more-modern serpentine belt with an automatic spring-loaded tensioner for the accessories; and a Distributorless Ignition System (DIS). This revision to the engine increased power to 98 hp (73 kW).
