In 1991, GM created a new-generation small-block engine called the "LT1 350", distinct from the high-output Generation I LT1 of the 1970s. It displaced 5.7 L (350 cu in), and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower combustion chamber temperatures and ...
Revisions to the engine for 1986 included roller lifters with a slightly smaller camshaft (.435"/.438" lift and 194°/210° duration at .050"), new heads with smaller, swirl-port intake runners, floating piston pins, and larger piston dishes for lower compression (8.0:1 v. 8.4:1). These changes increased torque to 250 lb⋅ft (340 N⋅m) but ...
The LT-1 is a Chevrolet small-block engine produced by the Chevrolet division of General Motors between 1970 and 1972. It was available exclusively in the Corvette and Camaro and was produced in relatively small quantities. It is regarded today as one of the greatest of the Chevrolet small-blocks, an engine that has been in production since 1955.
The 350 cu in (5,735 cc) B engine was, along with the 361, the first production B engine, first available in 1958. It had a bore of 4 + 1 ⁄ 16 in (103 mm; 4.06 in). The 350 is classified as a big-block engine. All parts except for the pistons are fully compatible with the 361. Vehicles using the B 350: 1958 DeSoto Firesweep; 1958 Dodge Coronet
In the mid-1960s, Chrysler decided to adapt the 318 cu in (5.2 L) small block V8 into a lightweight, high output engine equally suited for drag strip or street performance use. Its block was bored out to 4.04 in (102.6 mm) but its 3.31 in (84.1 mm) stroke left unchanged, resulting in the 340 cu in (5.6 L) engine introduced for the 1968 model year.
These pistons can survive mild detonation with less damage than stock pistons. 4032 and hypereutectic alloys have a low coefficient of thermal expansion. This allows tighter piston to cylinder bore fit at assembly temperature. The "2618" performance piston alloy has less than 2% silicon and could be described as hypo (under) eutectic.
An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel. This cylinder block is driven to rotate about its axis of symmetry by an integral shaft that is, more or less, aligned with the pumping pistons (usually parallel ...
The 322 Fireball V8 in a 1956 Buick Century. Buick's first generation V8 was offered from 1953 through 1956; it replaced the Buick straight-eight.While officially called the "Fireball V8" [1] by Buick, it became known by enthusiasts as the "Nailhead" for the unusual vertical alignment of its small-sized valves (Originally it was known to hot-rodders as the "nail valve", because the engine's ...
