I'm working on a friends Busa engine and i forgot my manual at home showing me how the timing marks line up. I know how to line up the marks on the side cover. But i want to make sure i'm at TDC by using the cam sprocket marks also. I'm pretty sure the intake mark is supposed to be at 12 o'clock and the exhaust marks are at the 3&9 position.
HELP!!!!!
