going from stock 340 to 408 stroker

i'm buying a 72 demon and the first thing i want to do is drop in my 408. i have already ordered a centerforce clutch but what else do i need to beef up. the car is an orignal 340 car not a clone so will it have a decent driveshaft? will the flywheel from the 340 work on my 360 based internally balanced stroker. it has the factory 8 3/4.

the car will be a street brawler but will also see the track a few times a year with street tires, no slicks.
