Ford Performance Parts 347 C.I.D. 350 HP Sealed Long Block Crate Engines M-6007-S347JR2

Part number M-6007-S347JR2 from Ford Performance is a new, factory-sealed 5.7-liter small-block at 347 cubic inches, built around a cast-iron block and cast-iron cylinder heads for spec-series racing classes where the rulebook calls for a tamper-evident engine, rated at 350 HP on a 10.5:1 compression ratio. What's in the crate A hydraulic roller camshaft rides on OE-style roller lifters inside, and the distributor, harmonic balancer, oil pan, timing cover, and carbureted intake manifold are already mounted, along with the valve covers and water pump. A carburetor is not included, and the throttle body, flywheel, flexplate, computer, and wiring harness are missing too, so a builder supplies the carburetor and remaining ignition components separately. Who it suits Because the seal has to stay intact, this engine is aimed at competitors running a spec-series rulebook, along with classic Mustang owners and street builders who want a carbureted Windsor without opening the long block themselves. Ford Performance recommends premium fuel of 91 octane or higher. This isn't a street-emissions-certified build, so keep it in off-road or sanctioned-racing service rather than daily traffic. Sold individually, it drops into applications already set up for a Windsor-family small-block. Common questions Is this engine fuel injected? No, it runs on a carbureted fuel system; a carburetor itself must still be purchased separately. Does it include a transmission? No, the transmission, ECU, and wiring harness are not part of this package.
