that can't be the case because i know of more than one in the 490s range
Dimensional you can go past 500, it depends on combination and how far over square and cylinder wall thickness the builder is willing to go. The majority I see and read about are in the 470 inch area. I currently am day dreaming a symmetrical SBX build of this variety.

^^ yup, you could go 525ci if you wanted a TQ monster, not much good for a high RPM drag deal
