OK, I'm dumb, need help

Been a Mopar nut all my life but have never really paid much attention to /6. Am considering a performance build of a /6. Have looked at the Clifford complete setup and am impressed but I would like to know what more is out there. Is more performance available? Can it be stroked? How about more cam? compression? Is better ignition available w/o a plastic drive gear? How far could a person go? Thanks for the input.
