Timming chain should be correctly aligned when the cam is pushed back to where the strocket contacts the front of the block. Is the crank sprocket push all the way back onto the crank?

How are you measuring the end play now?I like to measure off of the back of the cam before I install the rear cam plug Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)

Lots of ways to get the job done, if you have the right tool selection needed to get it done that way Good luck Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
