I like the rocker idea... But as I said, the cam isnt a big deal. The way you build power is push more air in, and keep the cylinder sealed. Which is why the others all end up around the same size. The same cam in a 2.2 Turbo II could make 190hp, or 300 or a lot more. It was all the turbo and electronics. It's not that I dont think there's room to improve, I just think you're concetrating on what's easy (ok, relatively speaking...lol), rather than what needs attention first.
