Could someone let me know what this pulley fits other than the 1970 Z/28 350 370HP engine. The gm catalogue says 454 but does not specify which engine. It is stamped 3995647AP on the flat outward facing side of the pulley with a P right across from the part number. Is this the same one on the 1970 L78 camaro engines also. iI thought the LS6 used an 060 pulley. Did the LS6 use 2 different pulleys. The pulley is definately deep groove. Thanks.

Bringing this question back to life..

Is it possible that my July built LS6 would of had this pulley? I know The 3976060 AP pulley is the known correct one for a 70 LS6 but the 3995647 AP is the superseded pulley... Just didn't know when the cut off date was for the 060. Thanks!
