On the right way, flex plate is arching forward at higher rpm, use to see it a lot at dealership

Makes sense...and easy enough to test. If the bolts are hitting the converter when it’s stationary, it is the converter that has ballooned. If there is normal clearance, the flew plate is shifting at high rpm (and I would get a new one).
