It has a 10.3:1 compression ratio. Its fuel economy is 4–6 km/L (11–17 mpg ‑imp; 9.4–14.1 mpg ‑US) in city, and 7–9 km/L (20–25 mpg ‑imp; 16–21 mpg ‑US) on highway. [citation needed]. Holden also produced the 3.2L engines that were used by Alfa Romeo as the basis of its JTS V6 engine. Applications:
In 1966–1967, the 1-barrel was replaced with a 2-barrel Rochester 2GV, giving the engine a 5-horsepower boost to 160 hp (119 kW). The V6 was dropped after the 1967 model year in favor of a conventional 250 cu in (4.1 L) inline-six engine built by the Chevrolet division, and the tooling was sold to Kaiser-Jeep .
It is Chevrolet's last production first-generation small-block. The cylinder heads feature combustion chambers and intake ports very similar to those of the LT1 V8, but lacking the LT1's reverse-flow cooling and higher compression. As such, the L31 head is compatible with all older small-blocks, and is a very popular upgrade.
The engine came with 543797 (4-barrel) and 9770716 heads for the tri-power and special exhaust manifolds and a 7H cam with 292deg. intake duration and later 1964 L with 288deg intake essentially the same as the 068 cam. #9770716 aka "716" heads featured a 170cc intake port volume, and were considered a milder "street" version of the vaunted ...
The bore and the stroke was 88.9 mm × 88.9 mm (3.50 in × 3.50 in), making it a square engine. The block deck height was extended and longer conrods were fitted 158.75 mm (6.250 in) between centres. A Bendix Stromberg two-barrel carburettor was used in place of SU carburettors. [11]
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 4-barrel versions had a larger diameter harmonic damper, the 2 barrel only a balancer hub without the rubberized outer ring.
The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth. The barrel is closed on one end by the cylinder bottom (also called the cap) and the other end by the cylinder head (also called the gland) where the piston rod comes out of the cylinder. The piston has sliding rings and seals.
US dry barrel: 7,056 cubic inches (115.6 litres; 3.3 US bushels) . Defined as length of stave 28 + 1 ⁄ 2 in (72 cm), diameter of head 17 + 1 ⁄ 8 in (43 cm), distance between heads 26 in (66 cm), circumference of bulge 64 in (160 cm) outside measurement; representing as nearly as possible 7,056 cubic inches; and the thickness of staves not greater than 4 ⁄ 10 in (10 mm) [2] (diameter ≈ ...
