Our 351w Dart SHP block stroker 427ci short block is designed for 600hp+ vehicles looking for a strong foundation for high horsepower. This short block is neutral balanced and ready for your big horsepower street or race car. The extra strength of this setup relies upon a scat 4340 forged steel crankshaft and set of 4340 forged steel H beam rods with arp2000 capscrews along with the Dart SHP 4 bolt main 351w block. This is the premium 4 bolt iron block available for 351w based motors and can handle upwards of 1200hp with all the parts included. Rings are gapped for boost. A full "blue print" build sheet with all clearances is included. The block has been fully machined after receipt from dart including: bore/hone with torque plates, square deck to the right rms for MLS gaskets, and a full deburr is done on the whole block to take away any sharp corners as well as at the top and the bottom of the cylinders. Finally all plugs are installed with sealant and a new oil filter adapter and Mahle rear main seal is installed.
