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 changed to cast iron except in a few rare cases.
The engine had MPFI (multi-port fuel injection), which gave slightly more power and better fuel economy, and two valves per cylinder. The engine had a bore and stroke of 4 + 1 ⁄ 4 in × 4 in (108.0 mm × 101.6 mm), producing 290 hp (216 kW) at 4000 rpm and 410 lb⋅ft (556 N⋅m) at 3200 rpm. It was used by Mercury Marine, named the ...
The engine has a bore and stroke of 93 mm × 69.9 mm (3.66 in × 2.75 in) and a bore spacing of 108 mm (4.25 in). [11] McLaren and Ricardo redeveloped the M838T engine for use in the McLaren P1. The engine has been upgraded to optimise cooling and durability under higher loads.
Design features of the B and RB engines include 17 capscrews per cylinder head, a cylinder block that extends 3 in (76.2 mm) below the crankshaft centerline, an intake manifold not exposed to crankcase oil on the underside, stamped-steel shaft-mounted rocker arms (race versions used forged steel rockers), and a front-mounted external oil pump driven by the camshaft.
The naturally aspirated GMC four-stroke diesel engines were added to the General Motors truck line for the 1965 model year. As introduced, the D351, D478, and DH478 all shared the same 17.5:1 compression ratio. [10]: 34 Although they shared similar displacement, bore, and stroke dimensions with the gasoline engines, very few parts were the same.

In 1958, Chrysler introduced its new wedge-head B Block engine, which was implemented in the Dodge and DeSoto lines. The following year saw the introduction of the RB Block in Chryslers and Imperials; this was a modified B Block with a raised deck resulting in an increase of stroke from 3.18 inches to 3.75 inches. In 1960 and 1961, Chrysler ...
Starting in 1970 for the 1971 model year, the stroke of the V8 engine was increased from 3.6 to 3.9 in (91.44 to 99.06 mm), thereby increasing the engine capacity to 6,750 cc (412 cu in). Known as the Six and Three-Quarter Litre or simply the Six and Three-Quarter , it is the most widely produced and well known of all the versions.
