2008 Silverado 5.3/4l60e the engine had failure due to lifter eating lobe off cam . Wanting to go back with a 6.0 . Looking for any pointer as to the best year model 6.0 that would be most compatible swap and any pointers like if the pcm would have to be segment swapped of if any custom harnesses would be needed . I?ve tuned trucks but never been involved in a swap .
