here is some brand new technical info for this new site.
A couple weeks ago Eli and I installed a cam shim on his car. This cam shim is make to fix an engineering flaw in the 4.6 DOHC. With the shim in it correctly applies tension to the upper part of the passenger side cam chain.
Here are some pics of the installation
This first pic is of the drivers side valve cover, with the spark plugs removed, and passenger side fuel rails removed to get the FPR out of the way enough to take the valve cover off.

here is the valve cover out of the car, that is the valve cover gasket that is kinda just hanging there in the cover

Here are the cam shims that I make in my hand.

here is a pic of where the shim goes. there are only the two bolts that you have to remove to install the shim.

Looks like in this pic i am taking the bolts out

Sliddign the cam shim into place...

here I am working away like a slave on Eli's car.

Unfortunatly I have installed two shims on mark VIII's and still do not have dyno results. Eli noticed a lot smoother idle, but HP figures are hard to guess. This shim helps to provide a more accurate timing to the passenger side bank of cyl's. With this cam shim it increases max rpm from 9250 to 9500 rpms's which is when the valves start to float with stock valve train.
