Is it just me? I can't see the timing slot on the crank pulley. The cam is spot on for alignment so that part is sorted. There's no CPS on these engines, it's all spark timed off the cam and it's relation to the distributor. Check your distributor leads. I'm sure #1 should be up on the top of the distributor cap. If you've swapped the firing order it will act like the distributor is out half a tooth (if I got it wrong someone will set me straight )
