I have A 502 stroker that has a milodon timing gear set. It was a surprise when I pulled the cover to say the least. i am replacing the cam and I don’t see any markings to indicate positioning like on a normal timing set. There are a couple dots on cam gear but nothing on the crank gear. In my research it seems like a difficult process to set the initial timing with tools I don’t have. Is there a way around it since the cam gear is already set for the cam that’s in it?
