7.3's are great but like stated can lacks power but can also make gobs of it. 6.0l great motor if you treat it right and fix the known problems and are a lot easier to make power. And once again cummins are a great motor and can make power even easier. So basically ya I just repeated what said above hahaha sh1t.
