Slant Six Forum :: Question for Doc r.e. his homemade cam "stops"

: The ball-screw does end-up in the "X"
: but you need to find dead center to the cam
: bolt hole.
:
: The way I do that is by using a piece of
: 7/16-14 threaded rod with a point machined
: onto the end of it. I install that into the
: end of the cam and install the cover over
: it. Now it is a simple matter of pushing the
: cam forward and "center punching"
: the backside of the cover, the punch mark it
: leaves is the place to drill your hole.
: You must also select a grade 8 bolt and grind
: the face of the head smooth.

Doug... I have a couple old junk timing covers laying around that I can drill on if finding the right location is just a hit-or-miss proposition, but I was wondering: is the cam bolt, by any stroke of luck, located directly under the intersection of the stamped "X" relief on slant timing covers? I've scrounged some extra rocker adjustment bolts @ the boneyard and some appropriate nuts @ the hardware and am gonna use your "anti-cam-walk" bolt idea on my next engine. Thanks. ---Red

I have never used a cam stop and never had any trouble with cam gear or oil pump....up to 7000 in my old car.
