Here's our 454's bottom end all buttoned up. Because the Motown block is externally identical to standard small-block Chevy blocks, all OE-spec accessories bolt up to it, such as the timing cover and snazzy Milodon oil pan. A Manley double-row "True Roller" timing system is behind the cover. Next month, we'll finish the assembly, bolt on the injection system and head for the dyno to see what this huge small-block is worth.
