Anyone have the 1972 Hot Rod Articles showing Mopar 305 build?

When I worked at Keith Blacks around the mid 70's, we were doing billet small block MOPAR cranks for ?Petty? I believe. The billet chunk of steel started off at better than 400 pounds. What they ended up at I never found out, nor did I find out the stroke or any other specs. I was racing small blocks back then (still am actually), but I couldn't get any info from anybody there.
