Chevy 350 block. 4 bolt mains and single piece rear oil seal. Crankshaft present and included with the sale. 7 rods and pistons also present. Looks like it was rebuilt and failed soon after. Requires a liner/sleeve in cyl #8 due to a broken rod (see picure) and other bores would benefit from a re bore. Delivery price is for UK mainland on a pallet
