We have a 23° 408 that made 702hp on the dyno. Old set of worked -10 heads. I suspect that if a 4-7 swap would net us 30hp on this motor we would probably spring for it. I really don't think it is there to be had that easy though. You are right on a motor that has a better potential of gain the increases you can see are greater.
