What are you wanting to shim ?.. the pump away from the block for clearance of the timing chain or the bypass valve in the pump ?

What he said.. You can make your own, but knowing how much to add is the question, I think I read how much on another thread. search for it.

With a new stock LS6 pump in my LS1, I am getting over 80+ cold / Startup and around 65 warm / idle. Using Penzoil syn 5-30w.

Warning, too much pressure is not always good thing.
