The only motors that got weights on the Convert were cast crank post 72 motors (440's) 440-6 motors were internally balanced. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

That thing shook so bad, you could not have missed it, or mistaken it for a dropped cyl, etc.

Joe Yep , starting with 70 the 440HP and 6pk engines were external balance and had weighted dampners AND converters .

The flex plate has a cut-out on the opposite side to mimic the weights on the stock converter. It is nice and sturdy, unlike the stock flex plate. Joe Last edited by jlatessa; 09/23/13 05:54 PM.

Joe I've heard of a lot of guys having problems with the B&M flexplates, converter bolt alignment and other problems I like and use the stock Mopar brand small (11 inch converter with the bigger 7/16 converter bolts) flex plates, both the SFI spec and stock street hemi non SFI specs, for all my race cars for the last 20+ yrs with no problems or failures I can't say the same for my friends who used the B&M plates on thier motors Mr.Cab Racing and winning with Mopars since 1964.
