I have that 200/205 504/512 112ls cam in my v6, along with mopar 1.6
rockers, krc ported heads, a ported intake manifold, sitting on top of a
fully rebuilt bottom end, as well as all the normal bolt ons. I really am
not happy with the performance I gained with this set up at all, I think it
has to do with the computer not liking the cam a whole lot, and there being
no aftermarket flashes avaiable for this truck (leach, b&g, ect). If I had
to do it again I would put the money into a nice 318 swap (which is in my
future, can ya say 390?)
