The 1973–1974 L82 was a "performance" version of the 350 that still used the casting number 624 76cc chamber "2.02" heads but with a Rochester Quadra-jet 4bbl carburetor and dual-plane aluminum intake manifold, the earlier L46 350 hp (261 kW) 350 hydraulic-lifter cam, and 9.0:1 compression forged-aluminum pistons producing 250 hp (186 kW ...
LS6 intake manifolds were also used on all 2001+ LS1/6 engines. The casting number, located on the top rear edge of the block, is 12561168. The SSC Ultimate Aero TT also utilized the LS6 block, albeit with an enlarged displacement of 6.3 L (384.4 cu in) and the addition of two turbochargers. [49] Applications:
All Ford small-block engines use two-valve-per-cylinder heads, with "2V" and "4V" designations indicating the number of barrels (or venturi) in the carburetor. The valves are in-line and use straight six-bolt valve covers. Coolant is routed out of the block through the intake manifold.
The composite upper intake manifold and cast aluminum lower intake from the L35 engine is also used on the LU3. The LG3 uses a cast aluminum upper intake and a cast iron lower intake. [7] The lower intake eliminated the EGR valve. The LU3 also received a "quiet cam" to help reduce vibration at both idle and high engine speeds.
They are commonly identified by the first three (319) or last three (291 for the 360-401 heads; 304 used a different casting) digits of the casting number. There was a U.S. auto industry-wide shift to lower compression ratios in mid-1971, so AMC increased combustion chamber size to 58-59 cc.
The Chevrolet small-block engine refers to one of the several gasoline-powered vehicle engines manufactured by General Motors. These include: The first or second generation of non-LS Chevrolet small-block engines; The third, fourth, or fifth generation of LS-based GM engines; The Chevrolet Gemini small-block engine
All generation-2 small-block Olds V8s used the same stroke of 3.385 in (86 mm). The big-block engines initially used a forged crankshaft with a stroke of 3.975" for the 1965-1967 425 and 400 CID versions; starting in 1968, both the 400 cu in (6.6 L) and the 455 cu in (7.5 L) big blocks used a stroke of 4.25 in (108 mm), with crankshaft material ...
The resulting engine was somewhat improved as to power and efficiency. The 5.9 L V8 engines followed suit in 1989, but also received the overall improved "308" cylinder heads (casting number 4448308) that featured significantly higher flowing exhaust ports and a return to the original 1971 (non-fast burn) combustion chamber.
