Sooooooooo, apparently I'm an idiot. I asked a question about a timing bb on the flywheel being 180 degrees off, as i thought my cousin was saying he found tdc near an arrow 180 degrees from the bb. I WAS COMPLETELY WRONG

On the flywheel there are these markings:

UIC. A bb with a number 5. And about 5 teeth in front of that is a triangle i was calling an arrow. He said he found tdc closer to that triangle. I have no idea where i got it being 180 degrees off.

So, can anyone explain that? Its a flywheel from a 53 truck on a 56 to 57 235 from a car. Could that affect it?

Sorry, you all must think im crazy for even thinking my original question was possible.
