What does a 647ap have to do with the question regarding 1969 ...647ap is a replacement pulley, and a sometimes accepted pulley for 1970 only.

Chevy started phosphating pulleys in 1965. I have seen them both ways. Tinnell phosphated the pulley on my Yenko. It was the original pulley that came on the car and still had the phosphating on it. [img]/ubbthreads/images/graemlins/scholar.gif[/img]

I have an original deep groove BB pulley that looks like it was dipped in black paint.

Wow...sounds like a real controversy. I will take the easy way out and go with the 60/80% gloss. Thanks guys.
