BluePrint Engines does not use familiar engine displacements (302 and 351 cubic inch) to specify Ford applications. Instead, these engines are listed with their "stroked" displacement.
BluePrint Engines high-performance engines offers engines that have been "stroked" to increase displacement and power. However, these engines use standard-sized engine blocks for easy bolt-in installation.
Ford 302 block has been stroked to 331 cubic inches or 347 cubic inches.
Ford 351 Windsor block has been stroked to 408 cubic inches or 427 cubic inches.
