That clutch will be fine for what you'll be subjecting it to. I run a 68-110R and it's perfectly capable.
I'm just weary of anything off that white car as its been thrashed to death. Can't see from the photos but as long as the friction face on the clutch and flywheel are OK and not cracked then it'll be OK.
All I know is for some reason the owner couldn't get on with the clutch and swapped it out for something different.
Capacity = engine torque output. Looking at your dyno you're dealing about 150lb/ft which is fine
