Default Ca smog

I've been wondering if anyone has passed smog with the only thing being changed is to a 383 with11:1 and a small smog legal cam?
Is it hopeless or should it pass? It will have stock cats on it

my LT4 with an "Hot cam", good cats, new opti, plugs and wires (basic tune up), bosch 3 injectors, new O2 sensors (all four) passed CA smog without any problem; a lot of guys claim to have passed CA smog with surprisingly radical combo's.

It should pass. Make sure it's tuned correctly and do a precheck.
