What exactly are you saying? Maybe I am misunderstanding, but I am also getting some numbers from elsewhere and I just want to find a decent range that hopefully lands me in the middle. I am also going to measure the inside of the balancer.
What he's saying is ignore the measurement on the Scat crank... It's oversized & most dampers would likely bind..
FWIW I agree with the majority of the posters, this isn't a Pontiac.. The key aligns parts, it doesn't prevent rotation...
And your 100 ft/lbs is a little light... Back in the day I remember the manual showing 175 ft/lbs... I looked at online specs & found 135 ft/lbs... So I checked an SAE reference based on the bolt being 3/4-16 & grade 8... And the SAE recommended spec is 420 ft/lbs...
