    Preferred 425 timing procedure

    The manual has a fairly elaborate procedure for checking or setting timing on a 425 which I have used with no problems.

    Is there another way to do this?

    Any idea why this procedure is used? I have my idea's why, but just curious if anybody knew for sure.

    Well it's probably pretty basic, like other older vehicles...

    If you want to check your timing, get a timing light, hook it up, loosen the dist. hold down bolt a little to advance or retard to where it needs to be,fire up the engine pull the vacuum advance line off of the dist. and and point the light at the timing indicator(?) on the timing cover, behind the waterpump........

    The timing proceedure is different from many cars of the same era. It is that way in order to provide maximum economy. There just isn't a simple foolproof way around it.
