Default Re: 70 BB chevelle block no.

The block casting number for all 454 1970 Chevelle LS5 OR LS6 is 3963512. It is located at the rear of the block on the drivers side. You should also see a casting date just off center of the block in the same region. The casting date should preceed the build date of your vehicle.
