# Ford Racing 347 Cubic inch BOSS Short Block

The Ford Racing 347 shortblock lets you build it your way by adding your choice of heads, cam, intake and oil pan. It's the perfect foundation to build a powerful 8.2 in. deck engine for your vintage muscle car, street rod, Fox Body or Late Model Mustang. This is the same shortblock used in the 347 sealed racing crate engines, Part # M-6007-D347SR and M-6007-S347JR. Nothing but the best parts are used inside including: forged crankshaft, forged I-beam connecting rods with floating piston pins and the BOSS 302 block. WARNING: This part is designed and intended for competition use only. It should not be installed on a vehicle that is driven on public roads and highways. Installation of this art on a vehicle driven on public roads and highways is likely to violate U.S. and Canadian laws and regulations relating to motor vehicle emissions.
