600 hp 318?

Thinking maybe I'd like to build a 318 and have it dyno'd... I have a 5.2 on the stand, and a LA roller from Drag Truck. Keep it fairly budget friendly, home-brewed, and see if it will turn 400 hp on pump gas with a "decent" idle. And.... most importantly it seems.... keep it a 318 !!
That's been done, it's not that hard to achieve those numbers. But 600 hp.... not as easy as some youtubers make it out to be
