Does anyone know the part number for a Dart Big M BBC? And has anyone run these solid top pulley setups? Interested in the differance between the solid one piece and the original 2 piece pulley.

I think the one peice uses a bushing instead of a torrington bearing behind the gear.

There the same, except for there's no adjustment for indexing the cam & making changes @ the track. I'm a dealer for Jesel, call or pm for a price quote...
