Thats weird because a few months back I ordered a converter for a street/strip 56 chevy truck and it came down to a 9 inch case and an 8 inch stator or an 8 inch case with an 8 inch stator.
We ended up going 8/8 and it’s amazing how it works. It’s a PTC and it’s their Drag Week converter. And that was picked because it’s 80/20 street.
