318 tuning question

on an LA engine turn engine to TDC take off dist cap see if rotor is pointing to number 1 (like small block chevy) if it isn't the timing chain may have jumped time, also turn crank both directions to check chain slop while watching the rotor... like said if its a stock nylon cam gear its toast its almost 60 year sold... nylon cam gears were toast in the 80s at 18-20 years old. So anyway if the rotor isnt pointing at #1 at TDC your cam position has moved. etc.
