My block casting number is 3970010 which was used on a 350 from 1969 - 1980 and on a 302 in 1969 (Z28).. I still need to get the casting date.. I'll update this post later on today with that..
So far looks good, I did find out that I had the high performance heads, I think they call it the "041" head which is the same as the double hump..
