I'm not well versed with the LS conversions and need some help from an LS Guru. I have a friend with a 2008 Denali that came with the 6.2L. It has a rod knocking and he has access to a 2011 Corvette 6.2L. He has concerns about DOD,VVT and any other issues with this swap. Both appear to be controlled by E38 ecm, so I'm thinking it should not be difficult. Anyone with experience / knowledge care to share some input on differences and obstacles for the swap would be appreciated.

Thanks,
Steve
