The firing order is 1-8-4-3-6-5-7-2 it will probably be cast in the intake as well. Number 1 on the cap will be on teh back side of hte cap. But to make sure, crank your engine over to TDC on #1 that 's the first cylinder on the left side and the harmonic balncer line should be up to 0. Then look at your rotor to make sure you know where it's pointing. It's by the one screw ifi remember right.
