With a finished weight of 36 pounds (16 kg), the block weighs 51 pounds (23 kg) less than the cast-iron block in the Chevy II 153 cu in (2.5 L) inline-4. Plating the piston skirts was necessary to put a hard iron skirt surface opposite the silicon of the block to prevent scuffing. The plating was a four layer electro-plating process.
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).
Compared to the FB20 engine, which is undersquare with an 84 mm × 90 mm (3.31 in × 3.54 in) bore and stroke for 2.0 L (1,995 cc) swept displacement, the FA20 is perfectly square with an 86 mm × 86 mm (3.39 in × 3.39 in) bore and stroke for 2.0 L (1,998 cc) swept displacement.
The 318-cubic-inch (5.2 L) 318 was released in 1950, replacing the 308. It shared the same 4 + 1 ⁄ 2 inches (110 mm) stroke as its predecessors but with a slightly larger 3 + 7 ⁄ 8 inches (98 mm) bore. It produced a maximum 136 hp @ 3400 rpm and 245 lb•ft @ 1400 rpm. [2] The 308 was discontinued in 1954 and replaced by the 324 cubic inch ...
Bore and stroke is 69 mm × 66.7 mm (2.72 in × 2.63 in), with a compression ratio of 10.0:1. Output is 51.5 kW (69.1 hp; 70.0 PS) at 6000 rpm with 95 N⋅m (70 lbf⋅ft) of torque at 4000 rpm. It features VVT-i, off-set type crankshaft which reduces friction losses and narrow-angle valves. Engine weight of 68 kg (150 lb); was achieved by using ...
The first Y-block on Ford automobiles and F100 trucks was the 239 cu in (3,910 cc) version as released in 1954 with EBU casting numbers. The Y-block was the same displacement as the old Ford Flathead V8 that it replaced but with a bigger bore and a shorter stroke (3.5 x 3.1 in).
Displacement (bore x stroke): 4.6 L (4,627 cc) (92 mm × 87 mm (3.62 in × 3.43 in)) [2] Block material: High pressure die casting aluminum block; Cylinder head material: Aluminum; Valvetrain: Dual Over Head Cam (DOHC) Valve timing: Continuous variable valve timing; Variable induction system; Fuel delivery: Multi-port fuel injection
While the block is iron, the cylinder head is made of aluminium alloy. The pent-roof combustion chambers are complemented by a cross-flow intake and exhaust layout. [11] The spark plug is located in the center of the combustion chamber. The firing order is 1-3-4-2, with cylinder number 1 adjacent to the timing belt. The 3S-GE was designed to be ...
