The 4.8L and the 5.3L are smaller truck versions of the LS1 and were designed to replace the 305 and the 350 in trucks. The 4.8L and 5.3L engines share the same Gen III LS-series engine block and heads (upper end) and therefore, most parts interchange freely between these engines and other variants in the LS family.
In 1966, General Motors designed a special 302 cu in (4.9 L) engine for the production Z/28 Camaro in order for it to meet the Sports Car Club of America Trans-Am Series road racing rules limiting engine displacement to 305 cu in (5.0 L) from 1967 to 1969. It was the product of placing the 283 cu in (4.6 L) 3 in (76.2 mm) stroke crankshaft into ...
The two transmissions cannot be differentiated from the outside. The 4L65E shares the same exterior parts but have stronger internals such as 5 pinion planets compared to 4 in the 4L60E. 4L60E uses a 6.5" depth bell with 6 bolts for non gen 3 LS applications and a 7" depth bell with 7 bolts for LS applications.
The Group 1 engines were the smallest in displacement and outer dimensions, and differed most significantly from the larger Group 2 and Group 3 engines by having only four main bearings (whereas the Group 2 and 3 engines had seven) [1]: 15 and a different firing order (1-5-3-6-2-4, whereas the others are 1-4-2-6-3-5).
The firing order of older big-block engines is 1-8-4-3-6-5-7-2 [63] while Vortec 8100's firing order is 1-8-7-2-6-5-4-3. Other upgrades of Vortec 8100 include a new 18-bolt head bolt pattern, longer connecting rods, different symmetrical intake ports, different oil pan rails, and the use of metric threads throughout the engine.
The engines were also sold for marine and stationary applications. In a 1938 reorganization, Winton Engine Corporation became the GM Cleveland Diesel Engine Division, and GM's Detroit Diesel Engine Division began production of smaller (50–149 cu in (0.8–2.4 L) per cylinder) diesel engines. Locomotive engines were moved under the GM Electro ...
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
The Chevrolet Gemini small-block engine is a dual-overhead cam (DOHC) V8 engine designed by General Motors.While technically a small-block engine because of its bore spacing of 4.4 inches, [1] [2] General Motors engineers do not consider it to be a part of the traditional Chevrolet small block lineage because of the substantial reworking, specialized development, and unique technical features ...
