    the timing marks are on the cam gear under the valve cover.

    take the plug out of the block and lock the crank. lock the cam in place via the cam locking inspection hole. put the chain on the gear until the 1503 marks are parallel with the cylinder head... pretty simple

    put the chain tensions in place before you button things up permanantly.. it's possible to have everything "timed" and the 1503 marks lined up but actually be a full tooth out of alignment

    Exactly!

    These 1503 marks appeared to be lined up... then I installed and tightened the tensioners and failed to re-check the marks.

    DON"T DO WHAT I DID!

    Mark... that is the RR light weight cam gear. It doesn't have the "1503" stamped below the horizontal hash marks like an OEM gear. The interesting part is the two horizontal hash marks were lined up with the head prior to installing the tensioners. If I had only checked them again afterwards. Also, as I've mentioned before, the biggest mistake I committed is thinking I could accomplish this task without the two locking tools

    Mark... disregard what I just posted! I went out to the shop and retrieved my stock and RR gears and realized I botched my explanation

    I need to re-examine what I did wrong before I put out bad info.

    jeff... on my RR leightweight gear, i can still see signs of the 1503 stamps.... urs are really totally gone from the lightening process? ... possible bc i've had a few gears and they are all different.

    i believe there's two different sets of hash marks on the gear?
