Smog Pulley 3927116 with broadcast code "AU" .....

Googled this pulley and really hard to tell if SB or BB and from what application it is from... Maybe the broadcast code reveals something?
Thanks!!!  Ted

Ted, this was used on L6, small block and big block cars. Since it was the smog pump pulley, it really didn't matter what engine it was mated to.

HERE'S MORE INFO for 1968 and HERE'S MORE INFO for 1969.

I was kinda hoping that for '68 L34 and 35 engines the pulley was applicable, but it is not on the tables... In '69 she looks good on the above Camaro 396s... 
Thanks ED...    T.

Really common pulley. Used for a number of years.

I have seen several different stampings for this pulley. In 1968 it doesn't have the AU code stamped on it. The correct smog pulley for the 68 L34 and L35 is 3917234.
