Would a GMPP LS6 crate motor-long block, with a July 2005 build date have the heavier (LS2) timing chain? I'll be assembling the bolt-on parts to install it in my Suburban in a few weeks, but didn't plan on replacing or upgrading any internals. Thanks for any info.
When changing the camshaft on my friend's 2004 ZO6, we bought an LS2 chain, but when we compared it the the original chain, it was the same.
Then when changing the camshaft on my 2001 ZO6, I installed the LS2 chain that was meant to go into the 2004 ZO6.
