Check out this Dude's Video on his Tear Down of a 6.2L Engine... But more importantly... Take a look around his Warehouse at All Those LS Engine Blocks. He mentions his Phone Number at the beginning of the Video and it might be worth giving him a call if you need various Hard To Find Parts and Pieces....or even a Short Block LS Motor to solve any 'Engine Disaster' (...like the one he is about to reveal...)
