I'm not building an SLC, but with the many members that have the LSx powerplants, I thought I'd pass some interesting information regarding a recent rebuild, especially related to the cam installation.
I attempted to install my camshaft into the 6.0L LS2 (2005) aluminum block before any other assembly (crankshaft in particular), and found I could not insert the cam beyond the second bearing. I found out that I had to preload the block with the main-caps torqued down to factory specs before the bores of the cam journals allowed the cam to pass completely through the block. Granted, I'm using new bearings, and this is not uncommon, but it was interesting in that the cam would have had to be driven into the bearings prior to the distortion of the block (main caps installed and torqued), but after the distortion, the cam slipped into place as it would any unloaded cast iron block.
