Thanks for the replies ya'll. I don't mind tapping the crank, I'm just a bit nervous about getting absolutely dead center. I had to drill out and retap my 350 a while back, so I've got some bits and a tap. Does it have to be dead center? Not sure what other problems I could create if I actually removed the crank to take it somewhere.
I'll try the heat/tap method first. He's taking his time to clean it up and paint it back. Figured since it was out, might as well make sure he changes the timing cover gasket cause it's sure alot easier to on a stand than in the truck
