I've used a ton of OEM street hemi in my race cars as well as several "Mopar" SFI tagged race ones up , I've never hurt one of either type or know any racer out here that has that had a decent converter to start with work I have seen them cracked but we also found out why, like a missing oil pump drive bushing or cracked or worn out bushing shruggy
I know several local racers that bought and used the B&M 6 bolt plates that had problems with all of the B&M they used work
Not so with the Mopar brand race 6 bolt flexplates with the large (7/16 diameter) race converter bolts up
