SFI flexplate mandatory in all v8s Jan 2024

Let's look a few things here:

Mopar ring gear is attached to the converter. I can buy them from a number of sources. Not SFI certified, in any case.

Fords have 4 bolts on the converter..Possible a stronger deal.

You cannot modify an SFI part i.e. cutting a window or a door in a bell housing. How do balance an approved flex plate then?

Turbo Grand National Buicks run way run way down in the 11's., as a V6 combo.
Same for Saturn Sky and Pontiac Solstice Eco-Tec 4 cylinder combos in Stock.

Seems to me that this should be done by ET, rather than singling out a particular brand or two..Maybe 12 flat ET..Not by class or eliminator like the stupid roll bar rule.

Just a thought or two, but whatever anybody does , don't show this post to the NHRA lawyers or insurance company..They're all pacified now.
