360/727 flexplate question

does your new converter have weights on it for the externally balanced 360 crankshaft?

and does it use 5/16 threads or the larger 7/16 threads bolts?

mopar sells a SFI model that is for the larger 7/16....and to be used with converter that has weights on it..

b&M sells one for converter with weights on it that has both small and large bolt holes..

b&m also sells one for converter with NO weights on it...and has both small and large bolt holes...

make sure you get it right.......
