The 4.6 L; 278.6 cu in (4,565 cc) L37 (VIN "9") was the original Northstar. It is tuned for responsiveness and power, while the later LD8 is designed for more sedate use. The L37 code had been used on all high-output transverse Northstars, even as the exact engine specifications evolved. The compression ratio for the L37 is 10.3:1 for engines ...
A Regular Production Option (RPO) is a 3-digit standardized code used by General Motors to designate vehicle options & modifications. RPO codes designate how a vehicle is built, and they've been used on dealership order forms and in assembly plants since at least the 1950s (see Corvette C1).
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 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 Motive Division (EMD) in 1941, while Cleveland Diesel retained ...
Introduced in 1963 on Pontiac's 389 and 421 cu in (6.4 and 6.9 L) drag racing engines, General Motors fitted it to the 1967 Z/28 before they used it on the L88 427 cu in (7.0 L) Corvette. It eliminated the production breaker-point ignition allowing greater spark energy and more stable ignition timing at all engine speeds including idle.
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 ...
A rear wheel drive bellhousing is displayed at right, and the integrated front wheel drive bellhousing is displayed at the lower right (in this case, as a part of the GM 6T70 Transmission). GM 60-Degree 2.8/3.1/3.4/3.5/3.9 L V6 (also used by AMC) Buick 3300/3800 V6; Cadillac HT4100/4.5/4.9 L V8; Isuzu all 3.2 and 3.5L DOHC V6
The 502—with a 501.28 cu in (8.2 L) total displacement—had a bore and stroke of 4.466 in × 4 in (113.4 mm × 101.6 mm) and a cast iron 4-bolt main block. GM offered it in their Performance Parts catalog, available as multiple crate motors with horsepower ratings from 338 to 600 hp (252 to 447 kW) and torque of 470 to 567 lb⋅ft (637 to ...
