Some 5.3 blocks will sonic test out to go 4.00 but no more when I say no more, 4.005 will start to push it.

Yeah problem is the block and IF there is enough material to do this or not. Getting a LS2 and then swaping your intake from your vehicle, if that's a truck or a car either will work and that will be the fastest and easiest way to get the power and reduce the weight by 100lbs at the same time.
