see i just lost faith in ur knowledge… small block are the same dimensions externally…
so puttin a 327 in is the same as puttin a 350 in. its just smaller inside. 305-350-400 all the same outter dimensions. so in theory if a 350 fits, you could bore and stroke a 400 and have serious displacement in there.
just from ur comment i think u may lack the knowledge to bring this project to the light of day.
