The Z06 cam could be dropped in without having to change springs and pushrods etc? I know there is much that should be freshened but as I mentioned not the time or funds right now. Is the cam job a lot different than the traditional small block? What kind of gains could be expected? I had also read somewhere that going to an LS6 mainfold makes a difference?

Thanks
