My friend is a total scruby guy, he did this for me as a favor due to me being physically unable to do the work but there isn't a timing marker or marks on the harmonic balancer , on the balancer due to paint.
He got the number 1 piston top dead center then timed it to sound and smoothness, the car starts beautifully, idles great until it's put in gear, then acts like bad gas or spark plug wires crossed , he .ran those out 3 times to make sure that wasn't the problem, after the car gets going it smooth's out and runs like a top until you slow to turn or stop and it dies.
