Description

BluePrint Builder Series 347W/415HP Standard Edition carbureted crate engine and 4R70W transmission combos take the guesswork out of matching up an engine and transmission for your ride. Featuring a fuel injected Ford small block-compatible 347 (c.i.d.) engine that produces 415 horsepower, this standard edition builder series includes a polished pulley kit and 4R70W automatic transmission. The aluminum BluePrint Engines cylinder heads help produce a nice 10.0:1 compression ratio, with assistance from the hydraulic roller camshaft, hypereutectic pistons, and steel crankshaft. Altogether, this assembly produces 415 lbs.-ft. of torque. When you need or want a new powertrain for your Blue Oval ride, go with the authority in crate engines and their BluePrint Builder Series 347W/415HP Standard Edition carbureted crate engine and 4R70W transmission combos.
