Pushrods convert the vertical motion of the lifter from the camshaft lobe into valve movement. A V8 engine takes advantage of that by centrally locating a single camshaft in the middle of the engine ...

An engine's power production is directly proportional to its air-processing capacity. Internal-combustion engines consume both fuel and air, but the air is far more difficult to ingest than the fuel.

Engine performance is like a complicated formula in which each individual part plays a role in the final answer. Some parts of the formula affect the final outcome more than others. The valvetrain ...

Overhead cams are a more efficient method of actuating the valves than with a pushrod, but someone in Detroit never got the memo. And thank goodness they didn't. With production pushrod mills turning ...
