This is supposed to be a GM 350-290hp crate motor. It should not have a multi key crank gear on it.
Never assume the multi key crank gears actually will move the cam accurately,
by the desired amount. (they don't)
You want to move the cam accurately by first determining its real installed position first. By degreeing it.
