okay i run a 233/238 .600/.608 112lsa and it makes good power..better on the bottle in my 6.0
have a buddy that put a 242/248 .6xx/.6xx 110lsa....its basically the t-rex cam and he put down 440rwhp in a 6.0 with some good 243 heads, now that thing made some great power...dyno kept making and he stopped at 7k rpm...peak was at like 6400 and this is with the stock truck intake...he admitted the cam is not to big but the motor is to small for the cam lol, but he was saying when it shifted it would fall on its face for a sec till it hit 5k rpm then it would pull again
