pretty much covers it all. if ur doing the 4.3 to 6.0 swap id also recommend a new rearend as well. very nice write up and im glad u did this derek. this will save a bunch of people a lot of time scratching their heads like i did for a long time. its a great swap especially when u go from being one of the slowest to the one of the fastest and spend a lot less money getting there. i would recommend anyone that wants to do this swap read this post first THEN ask questions cuz it doesnt leave much to imagine cuz it covers the subject well. great job derek. i would even sticky this at the top admins.
