Timing Mark Dilemma

Keep in mind though, that dot to dot IS 180 out. TDC for #1 is crank dot pointing at the cam sprocket and cam dot 180 degrees away from "lined up" with the crank sprocket. Dot to dot is on TDC for #6. It's shown dot to dot in all the manuals for ease of aligning. But when you go to install the distributor, you need to rotate the crankshaft ONE complete revolution to get it in the #1 TDC position.
