I do not know if these have been tested & if so what RPM are they good for?

But, these might be an option?

The SBC Chevy one I used is a 300 HP 350CI SBC 8" damper.
You would need to make brackets & pulley changes to make it work, a lot of work I.M.O.
Their are no V-grooves for belts on SBC dampers.
I was desperate to get my 250 to turn past 5500 RPM so I improvised & installed a SBC damper.
