trying to pull ponnies with little cash

a 318 out of a 84 ram i believe it only has 60000 miles but when i tore it apart is was nasty lookin but what im basicaly asking does any have any ideas on how to get somewhere around 400hp out it with spending as little as possible and as little machining as possible the car will b use on the street more and im hopping to put a 6spd in with mayb a 9 1/4 or a dana 44 with 4.10 or 4.11:burnout:

Mate,to be honest a 400hp 318 is gonna be a pretty nasty engine and it's gonna cost!!!
