1968 318 water pump?

I might be wrong, but i thought the balancer marks were 90* different from the early to late setups? I know you guys will let me know.....

Maybe time for a well placed timing tape. :D

That's the thing you can easily make one and it might have been wrong anyhow, either manufacturing tolerance, or "slipped" balancer ring. 20 minutes with a piston stop.......................
