Chevy 396

The 396 is sitting in my dads dually,he bought it in the late80'searly 90's,from panella racing,since then its been bored some,427 vette heads,n intake with work done,n i have tons of carbs here,the big block has cyclone headers (wich will not fit driverside),n he we have super t-10's,borg warner t-10's,other stuff etc..correct me if im wrong i thought a 440 was wider than a chevy big block??i looked today doesnt seem to wide,i know how to weld,a few of my uncles are mechanics,exactly how hard would it be to cram this engine in there?ive made a deep sump oil pan,fro 2 n some metal,from osh..so i can do that part,would fenderwells work?so what im hearing is its not gonna happen?
