One other minor difference between engine types is that the overhead valve engines have a lower center of gravity owing to the cam timing gear chain and pushrods being low in the engine performance cars like the corvette have a very low center of gravity giving them excellent handling grip and safety which they owe in part to the engine. As the camshaft spins its lobes move the lifter 20 which moves the pushrod 17 which hits that rocker arm 16 which is pivoted on an axle 16 to push down and open the valve 13 whats the difference between an engine and a motor what is the difference between v6 engines from different manufacturers. Ohv or pushrod overhead valve ohv or pushrod cams are common on simplified v style engines the camshaft resides at the center of the v usually at its base and as it rotates it pushes rods hence the pushrod name that in turn push against rocker arms that open and close valves in the engine head to either side of the v. When talking about mustangs and v8 motors they break down into two categories pushrod or modular starting with the 289 back in 1964 and finishing with the 50l in 1996 every v8 mustang between those years was equipped with some form or another of a pushrod engine. You can drastically tell the difference between them when you step on it i prefer pushrod motors because the power is there all the time no waiting lots of gm motors are this way too including the vette camaro and trucks the pushrod motors can be just as efficent as ohc motors and deliver power sooner the ls1 and ls6 are perfect examples
