I think you will find the biggest you can easily go to with an 88 is 95ci. To get to a 103 or bigger requires a longer stroke crank which is much more expensive.
Have a search through these threads and you will find a few engine specialists who do this sort of stuff every day. Contact one of them and ask their advice. They can probably supply a kit tailored to your requirements.
There is a thread over in Touring which asks a similar question, which is worth reading. It is worth searching in the main forums as this topic pops up quite often.

Or you can go to a 98" without pulling the crank, and see numbers as good.
Our American Iron Magazine build, 98" went 112 ft/lbs 122 hp, sae.
4 3/8" stroke(107") would strike much harder, and make another 10 ft lbs over a broad band. Peak has shown 122/126 sae.
Something to think about...........
