Okay, neither have a lot of guys here, I suspect.
It only has two opposing counterweights, front and rear.
The flex has a big balance weight on it. I wouldn't want to fool around with that bit of Pontiac engineering ;-)
TCI makes an SFI for the 400, which is the same except they are internally balanced.
This brings us to modifying an approved part. I see that this would have to be re-done every three years too. It's not gonna pass re-cert.

I seem to remember hearing that the perp in the Texas was invited to the barn for a look see. Now supposing one comes apart next year, you can bet it's coming apart too.
If they happen to find a modified SFI unit that failed, who do you suppose is going to have to pay that fine?
There are at least three of those 301 cars out there. These are 6 grand in the lights, max combos. What are they supposed to do ?

As my lawyer would say "arbitrary and capricious"
