Our customer in CA just ran his C7Z that has our heads/cam/ported blower/cooling/ and bolt on package and the 9.7 is what he put down! This is on a stock trans, converter, axles tire with a 15'' non beadlock setup. DA was also 19xx and this package is so easy to drive every day with zero quirks at all.
