How much power will these parts make?

My friend has a 87 carbed 305 Trans Am. How much power do you think he'll gain with heads, air intake, edelbrock carb and headers? He has the parts in a box, but I dont have the names of them off hand. (I know that there are major differences between one make/brand and another.) But, assuming the parts are decent, how much power are we looking at?

Thanks!
Bill

well if your going to swap the heads and inatke do the cam also, and a good heads/cam 350 should make about 400 hp

Yea, a decent 350 with cam/heads/intake/carb and headers should put out around 400hp at the crank. Maybe a little more or a lot less depending on the actual components.
