Default Punching out an Evo

Can a stock HD evo motor be punched out to a 103?

3.812 x 4.5= 103",the biggest you can go without splitting cases or boring cases on a evo is 85"

I have this customer that insists that you can bore out an evo to 103. I was just wondering if this was possible and if not, why.
Me? I play with cams, carbs, gears, and ignitions to get my bikes to go faster.

We've built 103" Evo's, and Shovels.
5" stroke, 3 5/8" bore S&S 103" Hot Set-Up, or Sidewinder kit.
Pick your cam, heads, compression, and HOLD ON!!
Instant torque, any time in any gear, like turning a light switch on, so much that not all folks like that.
