The optional "Power Pack" M-code used a four barrel Holley carburetor and was rated at 182 bhp (136 kW) at 4,400 rpm. [ 9 ] In 1956 the U-code was updated to produce 173 bhp (129 kW) at 4,400 rpm and 260 lb⋅ft (353 N⋅m) at 2,400 rpm with a manual transmission behind it or 176 bhp (131 kW) at 4,400 rpm and 264 lb⋅ft (358 N⋅m) at 2,400 ...
The valves are in-line and use straight six-bolt valve covers. Coolant is routed out of the block through the intake manifold. The design was soon bored to 260 cu in (4.3 L) and again to 289 cu in (4.7 L), then stroked to 302 cu in (4.9 L), settling on the most common displacement offered until the engine's retirement in 2001, nearly 40 years ...
The ASME B16 Standardization of Valves Flanges, Fittings and Gaskets Committee, which operates under ASME’s Board on Pressure Technology Codes and Standards is responsible for standards covering valves, flanges, pipe fittings, gaskets and valve actuators for use in pressure services.
A crossflow T-head sidevalve engine The usual L-head arrangement Pop-up pistons may be used to increase compression ratio Flathead with Ricardo's turbulent head. A flathead engine, also known as a sidevalve engine [1] [2] or valve-in-block engine, is an internal combustion engine with its poppet valves contained within the engine block, instead of in the cylinder head, as in an overhead valve ...
Use of a standard 352/390 cam for use in passenger cars along with carburetor and distributor adjustment allowed the 360 to give performance similar to that of the 352 and 390 car engines. Rated at 215 bhp (160.3 kW) at 4100 rpm and 375 lb⋅ft (508 N⋅m) of torque at 2600 rpm (2-barrel carb, 1968).
Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Compression packing is rigorously tested to ensure effective sealing in valves, pumps, agitators, and other rotary equipment.
The valve size increased as well, to 2.11 in (53.6 mm) intake and 1.77 in (45.0 mm) exhaust valves on high-performance heads. Low-performance and two-barrel applications, the standard engine in full-sized Pontiacs, got 1.96 in (49.8 mm) intake and 1.66 in (42.2 mm) exhaust valves and pressed in rocker arm studs.
A diaphragm within the valve keeps the outlet pressure constant, and this delivers a constant flow to the terminal. The added advantage of pressure independent control valves is that, when fitted with an actuator, they replace the manual balancing valve and motorized control valve with a single valve, thus reducing installation cost.
