Acutually you can off set grind Chevy cranks for a little more stroke.
Take a 355 (+.030 350) off set grind it .090 and use small journal rods and you get 364 cubic inches.
Take a 468 (+.060 454) off set grind it .090 and use small block rod journal and you get 478 cubic inches.
The down side is special pin placement (compression height) but when we were running class (weight / cubic inches) it was a small advantage that was legal.

WOW !..Weight vs CI.....now thats one you haven't heard of in a while.

to me that was real racing.....and 468ci was considered HUGE MOTORS.
