Pushrods are found in an overhead valve 4-stroke where the engine rods actuate rocker arms above the cylinder head to actuate the valves. Lifters or tappets reside in the engine block between the camshaft and pushrods.
The camshaft in the cylinder block is usually beside and slightly above the crankshaft in a straight engine or directly above the crankshaft in the V of a V engine and uses pushrods or rods to actuate rocker arms above the cylinder head to actuate the valves. Lifters or tappets reside in the engine block between the camshaft and pushrods.
