I was pondering about getting a cam, either from lg, or one of the ms3 or ms4 cams. I have been told that I have to swap out my stall converter for a higher stall rpm speed in order for the whole setup to work? is this true? If so, what do you guys recommend? All I have right now is a halltech intake, and a borla exhaust. I will be geting headers, and maybe some heads on down the road.
