318/360 heads,with thumper cam

Thanks OldmanRick,so with everything said will my hopes for having around 300-350hp be right on,pretty close or what?what else would i need to get there?also will the 3.23 gears be ok with everything i have listed,or would this package be better with other gears?whats a good estimate in power,after milling,zero decking the block,headers,600cfm carb,and will the stock 360 intake be good for the power i want,whats a good intake manifold?
