Thinking about doing this 440 build at some point -- opinions needed

Pretty much what my motor is but i have a bigger cam and a smaller carb. I'd like to put a bigger carb on at some point. Guys here told me I'd be lucky to see 500hp. Who knows, i don't really care as long as it feels fast. I'll let ya know if a month or two what my seat of the pants dyno says.
When they say lucky to see 500 hp, hell, even if it’s just close to 500, your car is gonna be fast.
