I've been looking around as I am about ready to take my block to the machine shop for cam bearings, but which ones do I need for an LM7? Some websites say that the block needs to be a 4.000 Bore block for some cam bearings to work? With the LM7 being 3.780, what's the best plan of action? Call the local GM dealer and get some that way?

I'm running federal mogul sealed power 1898M cam bearings in my '04 LM7 (Gen 3 block)

You need to measure the block as there are 2 possibilities. Let your machine shop do it.
