I by any means am a machinist,I am considering one of the 440 source kits because they seem too be reasonably priced,I am wanting too build a 470 inch motor,nothing too fancy just needs too be reliable,turn key get in it and drive it ***** to the walls kind of driving.somewhere in the nighborhood of around 550-600 or so HP??would it be reasonable too asume that in stock form that the 440 source parts be capable of that without too much reworking?
