Chris--what rpm do you run up to with the z06 cam?I run my vette up to 6700--I see you are going to put in rockers--I've been using 1.8 crane gold rockers,dual ls1 springs and the matching pushrods(there is a kit from Crane with all the stuff matched up)with the z06 for about 30k miles and they work great.How much power did you pick up with the cam?I am considering doing the same thing to my truck.
