    Up until the 8PN there were only two cams used regardless of HP.

    You guys need to stop with the C models being all PEEC engines, that is not true. The 3ZJ and 8PN are both mechanical C models.There are also PEEC engines that are B models.

    Thanks for the info. I'm going to go lay eyes on the cam we pulled and see what #'s I can find on it.

    That cam number does not show up in SIS, that may have been one of those odd deals where there is no direct replacement part.

    No, that number returns no searches.

    The 100-7408 is the new version of the 3787, so yes it is used in quite a few engines.

    I've come across a cam listed as 1007408 100-7408 7W3797 7W3796. So I guess the 3797 and 3796 also cross?
