after years of tinkering on bikes, I'd really like to try to hot-rod out an old frame. I'm looking at an old Bianchi Campione d'Italia from the mid 80's, a beautuiful Puch as well as an equivalently old Serotta. The problem is I'm currently riding a Cannondale CAAD 4 frame I built up a few years ago with 9 speed Ultegra. I want to spend the off season cannibalizing wy CDale and moving parts over to the Classic frame. Obviously there's going to be some problems, and I know there will be a lot of incompatiblities, but what can I expect to spend and what will I need to do that might be beyond my abilities (ie spreading the rear triangle).

Sorry this is so broad, thanks for the help
