Umm.. I know a lot of people that push 450-500hp out of a stock bottom end. They've all lived for about 3 passes and cracked the blocks or had some major problem with the main caps walking even with a stud girdle.
If you want to do it, there is no real inexpensive way to make that kind of power. Get a 4 bolt main block to start with, and H-beam rods, forged flat top pistons, and a real heavy duty crank. Then worry about heads/cam/intake. Oh yeah, if its N/A wouldn't you have to rev a 302 to like 7,000 or so to make that power?
