advice: 500hp SB build

So again, what is the budget? A figure please...lol
I honestly don't know - 5k? The block is machined and ready. If I can use 'em, the stock rods were done as well. stock stroke balanced crank done and polished (I guess will need to be re-balanced with new pistions if I don't stroke), windage tray is there with the pan and HV oil pump, pickup, ignition, MP valve covers, dist. drive, Headman headers.

Need: heads, intake, carb, rockers, springs, push rods, pistons, rods(?), crank(?), cam, lifters, and any additional machining for the new parts.
