How realistic is this budget built ? 400hp 318

A 318 is often overlooked as a performance engine. I think alot of it has to do with the fact that Chrysler marketed it as there work horse 2 barrel V8. Put some hi compression pistons, decent flowing heads, and 340 cam and let those 318 cubes ring! 65'

i think we overlook it because for the same money you can build a 360 and get more power
it just doesnt make sense not too (provided you can find the cores for the same cost)
