Default Fatboy engine, help

Hi Guys, just wondering if anyone knows if it's a big job to change my 2003 fatboy 88ci over to a 96 ci ? I have a brand new set of 96ci cylinders and pistons, What else do I need and is it a good idea or am I just asking for problems ?

Thanks

I thought the 88 and 96 had the same bore. The thing that makes the extra cubes is the stroke of the crank. It went from 4 inches to 4 3/8.
