NORBI Posted March 11, 2003 Report Posted March 11, 2003 Whats the difference between pushrod engines and other engines. Quote
patgizz Posted March 11, 2003 Report Posted March 11, 2003 pushrod engines = they have pushrods = cam is down in the block. the cam pushes up lifters, that push up pushrods, that push up on a rocker arm, which pivots and pushes down on the valve stem to open it. "other" engines = ones with overhead cams. some have one that controls all the valves(one for an inline or one per bank for a V) and some have 2 that each control intake and exhaust. they don't have pushrods as the cam acts directly on top of the valve(in most cases).
