Oldsmobile V8 engine

I want to introduct something about Yacht. Yacht Axello 31CERTIFICATIONAxello 31 is delivered with a CE certificate and meets the requirements of European directive 94/25/CE for recreational crafts. The CE class A category certificate (unlimited Ocean voyages) is issued by Germanischer Lloyd.CONSTRUCTIONMultiaxial laminate/Isopthalic polyester resin for improved mechanical and chemical properties/NPG (Neo Penttyle Glycol) gelcoat for optimal chemical resistance against osmosis and mirror finish/moulded inner structure glued and laminated to the hullDECK EQUIPMENTS/S pulpits, pushpits and stanchions with lifelines/4 mooring cleats/teak toe rail/2 deck organisers/2 sets of clutches/2 halyard Harken 16 B STA winches on coachroof/2 genoa Harken 32.2 STA winches/2 genoa sheet tracks with genoa cars adjustable from cockpit/mainsheet traveller track adjustable from cockpit/compass on instrument console above companionway/1 winch handle bin/1 cockpit locker/1 gas bottle locker draining outboard/S/S bathing ladder/tiller with extension/grabrails on coachroof/te

The 1967 Toronado's 425 V8, the first post war front-wheel drive V8 application.
The Oldsmobile Rocket V8 was the first post-war OHV V8 at General Motors. Production started in 1949, with a new generation introduced in 1964. Like Pontiac, Olds continued building its own V8 engine family for decades, finally adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V-8's were manufactured at plants in Lansing, Michigan.
All Oldsmobile V8s use a 90 bank angle, and most share a common stroke dimension: 3.4375in (87.3mm) for early Rockets, 3.6875in (93.7mm) for later Generation 1 motors, and 3.385in (86mm) for Generation 2. The engine could be classified as a small-block, but Oldsmobile used a higher deck height for a 4.25in (107.9mm) stroke to boost displacement to a big-block-like 455cubic inches (7.5L).
The Rocket V8 was the subject of many first and lasts in the automotive industry. It was the first mass-produced OHV V8 in 1949; and was the last carbureted V8 passenger car engine in 1990.

Generation 1
The first generation of Oldsmobile V8s ranges from 1949 until 1964. Each engine in this generation is quite similar with the same size block and heads.
303

Rocket V8 303 engine
The 303-cubic-inch (5.0L) engine had hydraulic lifters, an oversquare bore:stroke ratio, a counterweighted forged crankshaft, aluminum pistons, floating wristpins, and a dual-plane intake manifold. The 303 was produced from 1949 until 1953. Bore was 3.75in (95.2mm) and stroke was 3.4375in (87.3mm). Cadillac used a distantly related motor which appeared in three different sizes through to the 1962 model year; though the Oldsmobile and Cadillac motors were not physically related, many lessons learned by one division were incorporated into the other's design, and the result were two engines known for their excellent power-to-weight ratio, fuel economy, and smooth, strong, reliable running.
The original Oldsmobile V8 was originally to be advertised as "Kettering Power" after chief engineer Charles Kettering, but company policy disallowed the use of his name. So the engine was sold as the Oldsmobile Rocket. The engine was available in Oldsmobile's 88 and Super 88 models, which acquired the nickname Rocket 88.
The 303 was available from 1949 through 1953. 1949 through 1951 "88" 303's came with a 2-barrel carburetor for 135hp (100kW) and 253lbt (343N). 1952 88 and Super 88 V8s used a 4-barrel carburetor for 160hp (119kW) and 265lbt (359N), while 1953 versions upped the compression from 7.5:1 to 8.0:1 for 165hp (123kW) and 275lbt (372N). For comparison, a 1949 Ford Flathead V8 produced just 100hp (74kW).
Applications:
1949-1953 Oldsmobile 88
1949-1953 Oldsmobile 98
1952-1953 Oldsmobile Super 88
324
The 324-cubic-inch (5.3L) version was also produced from 1954 until 1956. Bore was increased to 3.875in (98.4mm) and stroke remained the same at 3.4375in (87.3mm). All high performance 324s came with 4-barrel carburetors. The 324 was shared with GMC trucks.
The 1954 88 and Super 88 V8s used an 8.25:1 compression ratio for 170 and 185hp (126 and 137kW) and 295 and 300lbt (399 and 406N) respectively.
The 1955 upped the compression to 8.5:1 for 185hp (137kW) and 320lbt (433N) in the 88 and 202hp (150kW) and 332lbt (450N) in the Super 88 and 98. For engines built during the first part of 1955, the 324 skirted pistons had a reputation for failing due to the cast aluminum skirt separating from its steel interior brace. This problem did not appear until the engine had over 50,000miles (80,000km) on it. By late 1956, many Olds dealers learned about the problem.
Compression was up again in 1956 for 230hp (171kW) and 340lbt (460N) in the 88 and 240hp (178kW) and 350lbt (474N) in the Super 88 and 98.
Applications:
1954-1956 Oldsmobile 88
1954-1956 Oldsmobile Super 88
1954-1956 Oldsmobile 98
370
A special 370-cubic-inch (6.1L) variant called the 370 was used in GMC trucks alone, not shared.
371
371s were produced from 1957 through 1963. Bore was now 4.0in (101.6mm) and...(and so on) To get More information , you can visit some products about centrifugal slurry pumps, textile dyeing process, . The Yacht products should be show more here!
