Heads used on the high performance 409 and 427 engines had larger ports and valves than those used on the 348 and the base 409 passenger car and truck engines, but externally were identical to the standard units – but for the location of the engine oil dipstick, on the driver's side on the 348 and the passenger's on the 409/427.
All MEL engines had wedge-shaped combustion chambers formed between a flat head surface and an angle milled block deck (10 degrees off square with the bore axis), with the piston top determining the compression ratio and combustion chamber shape, similar to the Chevrolet Big-Block 348 combustion chamber, also introduced in 1958, and the later 409 and 427.
Also called the GM small corporate pattern and the S10 pattern. This pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block compared to front wheel drive installations.
Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some "big block"-sized V8's as well as some V6's and I6's. 200 I6 1978-1983 only, partial (4 of 6 bolts) pattern. 250 I6 (except Australian 250/4.1) 255 V8; 289 V8 - (made after August 3, 1964) - had 6 bolts holding bellhousing to block; 302 Cleveland (Australia)
The cylinder block is a chromium-nickel iron alloy with a 60-degree design. [ 10 ] : 34 It has a peak gross and net power output of 170 and 155 hp (127 and 116 kW) at 3200 RPM, respectively, and corresponding gross and net torque output of 310 and 290 lb⋅ft (420 and 390 N⋅m) at 2000 RPM, respectively.
The HD inline-sixes, later to become the first in International's long running "Diamond" series, first appeared in the C-30 truck of 1934. [9] Available in three different displacements (see table), they were renamed "Green Diamond" in late 1940 for the 1941 model year after a number of detail improvements. [7]
The Chevrolet Biscayne was a series of full-size cars produced by the American manufacturer General Motors through its Chevrolet division between 1958 and 1975. Named after a show car displayed at the 1955 General Motors Motorama, the Biscayne was the least expensive model in the Chevrolet full-size car range (except the 1958-only Chevrolet Delray).
The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the Chrysler FirePower (first generation Hemi) engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi ...
