Description

BluePrint Engines 50 state legal long blocks are designed and manufactured to factory specs for specified vehicles. They're built using tighter machining tolerances, higher quality components, and finer balancing of the rotating assembly to make them better than the original—while still meeting the description of a "replacement" engine. From Ford Windsors to Chevy big and small blocks, these assembled crate engines are available for a wide range of vehicles spanning a half-century. Select the recommended fitment, specifications, and options needed for your swap.
