What you saw, was slack in the chain, when the cam gear did not turn with the crank gear! Again, I hate to be the one to say it, but you need to add the timing set to your list of things done to your PA!! Be sure to replace the tensioner also. With all that slack, your timing is retarded and that will rob power! You will be surprised how much better it will run with a new timing set! By the way, please state your mileage again.
Good luck
