The 70s cast blocks were service blocks to replace blown up OE engines. They weren't OE in any production cars. Some of them were left over by race shops when NASCAR changed the rules eliminating 427s (anyone know when that was?) The nice thing about service blocks is that they have the extra ribbing and some argue also that they have a better alloy mix than the 60s blocks.
