440 in 72 Dart Swinger?

This is my first A body its a 72 Dart Swinger has the small block 340 with 727 transmission and 8 3/4 rear, what I would like to know is can you put a big block 440 into it without having to make large modifications?

easy swap using conversion mounts. headers are expensive though. but good small block headers are expensive too. you'll need a big block trans too. can always sell that 340 for some good money to fund the 440 build. there is nothing like a big block abody. they are so much fun and with use of some alum and large torsion bars it will handle on the street nicely..
