It used four-bolt main caps, a forged steel crank and forged steel connecting rods. The engine featured aluminum cylinder heads, with a semi-hemispherical type combustion chamber which Ford called the "crescent". These heads used the "dry-deck" method, meaning the coolant circuit for the block was separate from the cooling circuit for the head The "dry-deck" method of design is intended to strengthen the block by removing the open coolant jackets around the cylinder and reduce hot spots by providing more direct cooling. Each cylinder, oil passage and water passage had an individual "O" ring style seal to seal it tight. Although a head gasket is used, it only seals the cylinder for combustion so a failure at one point won't compromise the others. The Boss engine came standard with a single Holley 4-barrel carburetor rated at CFM mounted on an aluminium intake manifold that flowed well for its time. The Mustang's engine compartment was not wide enough to accommodate the massive Boss engine, so Ford contracted with Kar Kraft of Dearborn, Michigan, to modify 4-speed Cobra Jet Mustangs to accept it. Production of the Boss began in at the Ford Rouge plant, where front apron assemblies revised to accept the large Boss engine were installed during vehicle construction. These also provided a stronger and cleaner front structure, important considerations on such a performance car, and were coupled with reworked front fenders.
