how can i get 400hp out of a 318?

im looking to rebuild my 318 in the near future. i just want to know what you guys recomend for cam, intake, headers. pistons. and if i should bore, if so how much?, i want to be making 400+hp just dont know what it takes to do so.... and do they make turbo kits for 318? thanks

Going to have to bore and stroke it. I have the cam, intake, headers, carb, etc... and I estimate maybe 300 hp. That is probably optimistic.
