Nice job Mark, thanks for the pictures

Bill,
Here's three pictures of my coils-on-plugs setup, unpainted.  (Lest anyone
get
the idea of using garden hose for plug-coil connectors, they were for
mockup
purposes only.)  The brackets mount to the holes in the rotor housings
that
are normally used for knock sensors.  I understand these bolt holes are
only
on some of the 3rd gen engines.  So, you would have to find somewhere else
to
bolt to.  The bracket is made of 1/2" square 4130 tube.  The "wires" going
from the coil to the plug cap were made from springs which I stretched out
a
bit.  Since these coils are made to mount directly on the valve covers of
the
LS1, I didn't see any reason not to mount them where I did.  However, if I
start experiencing coil failures, I will most likely move them, or mount
them
on the plugs using shock mounts.
