Used Custom cam that was specified for a turbo 5.3 L83 engine in a 2014 Silverado. With an out of the box s475 and our own custom turbo kit this truck made over 700 rwhp with the converter unlocked at around 15 lbs of boost.
223/227 dur @ .050" .662/.633 lift on a 114 LSA +3
Later when we rebuilt the engine with some better internals we found that the lift was more than the factory rockers and valve tips would have liked as there was some wear so we swapped the cam to something with a bit less aggressive lobe and less lift. This would still be a great cam with a roller tip rocker however.
