Small block bottom build horsepower limit

I just want 500ish hp.... nothing insane.. well.. 500hp that i can beat for years and never worry bout :)
With the average parts available us eg. trick flows, 500 hp is the new reasonable goal.

Jesus that thing is awesome.... Hadn't seen it before
From the sounds of it, it makes it's 735-770hp by 7500 rpms which should put peak tq around 585 lbs-ft which is 1.55 tq:cid.
