A lot of Chevy engines around late 70,s early 80,s had timing marks straight up. You had to view between the water pump (long pump) & the timing cover. I also believe you have a miss match of parts. With the modifications you have on the engine, the specified marks are not much use any how. Set the timing to where it runs the best. If it pings on a hard pull set it back some. If it kicks back when you go to start it it is also too much. You can usually set it by feel. Also the on damper shone in the photo it appears the outer ring has shifted. The outer ring is generally even with the hub.
