Looking and gathering all the details on a 6.0swap. Tahoe has 220,xxxmi and the #1 cyclinder (lifters) is where the noise is coming from. We were aware of this, just not now, winter is on us, but anywho, What I found so far, go for the 07 6.0 almost all the sensors are int he same spot. Will deal with the 4L60E in the spring. Wife said, can we put a light cam in it then get it tuned? I said well yes we can. good low/mid rpm cam suggestions? We don't hotrod the Hoe, it may tow a camp trailer later down the road, but it is her winter/backup unit. Camaros don't do well in snow ;-) Anything I need to look for before say perchasing a reman/rebuilt long block? It will have the DoD delete. Thanks in advanced "BigJ"
