That's what I was thinking. It becomes a larger bore 88" when you bore the cylinder's and the cases. I wasn't sure about the cases, but I was certain about the cylinders. What happens when you add a stroker flywheel to the mix here. Or is it even possible with an 80" on top of the additional bore.. Thank you for the comments posted here Springer!

4.5" stroke will give you 93" & 4 5/8 will yield 96". There's a company that makes nikkaseal(spelling?) cylinders that are bolt on 85", no case boreing. Maybe Revalution Performance but not sure of the name of the company.
