[Shotimes] how to change cams?

[Zach Leahy]

Jason,

I have been in many a SHO motor, so let me say that this is a
reasonably large amount of work.  If you are pretty comfortable with
tools, go for it.

First, look at a 60k maintnance, and that will get you most of the way
there.  Yes you do have to take the timing belt off as it is attached
to 2 of the cams.  basically once you are stripped down for a 60k
(don't need to remove the water pump though) you will take the cam
gears off (3 10mm bolts each) and the rear timing belt cover off which
is a whole pile of 10mm bolts.  Then take all the camshaft bearing
caps off and also the 4 on the briver's end that hold in the
tensioner.  from there you can pick up the cams as a unit.

Depending on what you get with your cams, you will probably have to
swap the chain pullies onto them, unless your new set still has them
on.  There is an alignment link on the chain to help line it all up
when you put it back together.  It has been a little while, but iirc
the alignment links line up with the dots on the cams, which will be
the farthest passible apart.

Put the cams and tensioners back it, I don;t know the torque spec off
the top of my head, and torque it all.  This is also a great chance to
change in new camshaft seals.  New valvecover seals are not a half bad
idea either.  put the rear timing cover back on, and the cam belt
gears (they are pin indexed) and continue the reassembly per the 60k
installation.

Perhaps it would be a good idea to find someone who has done it before
to help you through it.  Where are you located?
