I am putting together a 1969 Chevelle and rounding up the parts for a 396 - non A/C. I have a 3955291AB crank pulley. Is this a true deep groove pulley?
My research so far says that it is.

Is there a 1969 2 groove BBC crank pulley that is not deep groove? If so, does anyone know the number?

Apparently the deep single groove water pump pulley is a 3976060AP ?
But then I see where someone said the 3947824BV or DV is the same pulley and that it fits small blocks as well? Is this true?

anybody up on this?

you may want to ask over in the restoration section. some of those guys are really sharp on this detail stuff.

good idea, thanks.
I posted the same question in Restoration and got difinitive answers.
