push rod ?

so now i have looked up all the part numbers and looked at push rods in hand and the three motors( two 318s and one 360) i have in their stock form all use the same push rod and its roughly 7.5 inches long.

the ones in the 360 i bought are only about 7 1/4 so they are about 1/4 shorter than stock length. Thats the problem with working on stuff you did not put together urself ughhh.

everything in the motor looks to be pretty new and stockish but what can you tell just by looking right lol. and i have no clue on the cam either but why would somebody put shorter push rods in ?? because of cam choice as it has the stock type non adjustable rocker arm shaft and rocker arms.
