Windage is a force created on an object by friction when there is relative movement between air and the object. Windage loss is the reduction in efficiency due to windage forces. For example, electric motors are affected by friction between the rotor and air. [ 1 ]
A structural windage tray is bolted to the bottom of the cylinder block to further improve the block stiffness, minimize NVH (noise, vibration and harshness) and help reduce oil foaming. To further enhance the stiffness of the lower engine structure, a heavily ribbed sump body is installed.
The 340 also used additional heavy-duty parts, such as a double-row roller timing chain and sump-mounted windage tray. Power output was officially stated as 275 hp (205 kW) gross for the 4 barrel. In 1970, Chrysler introduced a special triple carburetor version of the 340 with triple 2-barrels at 290 hp (216 kW) gross .
It had a 3/4-length semi-circular windage tray, heat-treated, magnafluxed, shot-peened forged 1038-steel 'pink' connecting rods, floating-pin in 1969, forged-aluminum pistons with higher scuff-resistance and better sealing single-moly rings.
It has smaller valves and stiffer valve springs than n/a 16V. Crank torque is 290 N⋅m (214 lb⋅ft) at 2950 rpm for the GT, and 280 N⋅m (207 lb⋅ft) for the FT. Other differences from the normal 16V redblock engine are that it uses a remote mounted oil filter (Away from block on exhaust side engine mount) and a windage tray.
In 1967, Pontiac moved on to a technologically simpler nodular cast iron (invented in late 1940s) crankshaft, which they continued to use until the Pontiac V8 engine was discontinued in 1982.The SD racing program was the source of factory supplied performance items such as 4 bolt main bearing caps and windage trays to reduce friction from ...
The Ford Boss 302 (formally the "302 H.O.") is a high-performance "small block" 302 cu in (4.9 L) V8 engine manufactured by Ford Motor Company.The original version of this engine was used in the 1969 and 1970 Boss 302 Mustangs and Cougar Eliminators and was constructed by attaching heads designed for the planned 351 Cleveland (which debuted the following year) to a Ford small block.

The F22A6 also has a windage tray in the oil pan, and stiffer valve springs to accommodate the more aggressive camshaft. In cars with an automatic transmission there is an oil cooler present on the back of the block as well. F22A7: 150 hp (112 kW) European domestic market engine, with more power due to less strict emission standards. (uses PT4 ...
