415HP from 318ci IS POSSABLE!!

So what is a good recipe for building a streetable 318, cam, heads, intake, induction, headers (size)..........This motor would have to make an easy 325 horse with at least 300-375 lbs of torque.....can this be done easily and not at the expense of high rpm operation. I would rather use the 318 I have than spend the change for finding a decent 360, as they are not very common around here........
