Is there anything I need to be aware of when swapping out? From my understanding since I'm keeping the stock cam, there is no need for a lash cap and its a simple remove and replace the pump.

Do I need to measure preload and shim accordingly or would matching the stock LT4 pump shims be ok?

Looking for info from those who have done this swap.

Thanks
What are your mods?
