This block is one of three displacements, 302/327/350, that underwent a crankshaft bearing diameter transformation for 1968 when the rod-journal size was increased from the 2 in (50.8 mm) diameter small-journal to a 2.1 in (53.3 mm) large-journal and a main-journal size that was increased from 2.3 in (58.4 mm) to 2.45 in (62.2 mm).
1977–2013 Chevrolet 90° V6 engine (derived from the Chevrolet Small-Block" V8; now marketed as GM Vortec V6 or Vortec 4300 or EcoTec3 V6) 1979–2010 Chevrolet 60-Degree V6; 1994–2005 Opel 54-Degree L81 V6 (used in the Saturn Vue, Cadillac Catera and Saturn L series) 1995–present Suzuki H (used in several models built for GM by Suzuki)
The next year, Chevrolet introduced a full-production long-stroke 3.1 L; 191.3 cu in (3,135 cc) version in the Pontiac 6000 STE AWD, with a 89 mm (3.5 in) bore and 84 mm (3.31 in) stroke compared to the 2.8 which shared the same bore, however with a 76 mm (2.99 in) in stroke. It was produced simultaneously with the 2.8 L (2,837 cc) in various ...
The block is changed, with sleeved cylinders in an aluminum block with a larger bore of 4.125 in (104.8 mm) and longer stroke of 4 in (101.6 mm) than the LS2. The small-block's 4.4 in (110 mm) bore spacing is retained, requiring pressed-in cylinder liners.
The DH478 shares the same 5.125 in × 3.86 in (130.2 mm × 98.0 mm) bore and stroke as the D478 with a total displacement of 477.7 cu in (7.8 L). The primary difference is the DH478 has an oil cooler standard, which is optional on the D478. The cylinder block is a chromium-nickel iron alloy with a 60-degree design.
Within 18 months, the design of the Chevy II was completed, including new 153 cu in (2,512 cc) four-cylinder and 194 cu in (3,185 cc) six-cylinder engines to power it. The 153 cu in engine had a 3 + 7 ⁄ 8-inch (98 mm) bore and 3 + 1 ⁄ 4-inch (82.6 mm) stroke, with two overhead valves per cylinder actuated by pushrods and a 1-3-4-2 firing order.
Offered also in 1967, the 230 cu in (3.8 L) OHC 6 shared internal dimensions with the overhead valve Chevrolet straight-6 engine it was based on, [citation needed] but had unique cast iron block and head castings. Only the large cam carrier/valve cover was aluminum. It used a jackshaft (outside of the block) for oil pump and distributor drive.
