SFI flexplate mandatory in all v8s Jan 2024

And I've got a "Billy question" here, since this "issue" involved the starter ring gear and not the actual flexplate itself, are Mopars going to have to have SFI approved torque converters?[/QUOTE]

Billy, I've never seen a ring gear come off a Mopar converter but that doesn't mean it couldn't happen. I have seen the external balance weight come off one, pretty heavy chunk just held on be two spot welds. Made a mess of the case.

So... enlighten me, because it never occurred to me, is the counterweight on the converter?...
If so... how do you guys balance your rotating assembly?

Haven't worked on many Chrysler products in my time, last was in the late 70s and not performance stuff...

Hi Jim! Steve Stasko posted a picture of one "coming off" a couple of pages back.

There are stamped plate made where you could weld the Mopar ring gear in as many places as the approved GM items. Then ,there are some builders that will attach the ring 4 or 6 light gauge tabs...Guess which one the racers are gonna want...
