1970 454 4 bolt block casting #3963512 dated L-8-9 with no visible numbers on the front pad or down by the oil filter. The block is .030 and great for a restoration. I do have #7416 cranks and square port #3964291 heads if needed. Shipping will be to a local truck terminal in your area or to a business that has an unloading dock or fork lift if their is room for the truck to deliver.
