Chevrolet Performance Bowtie Big Block Chevy Cast Iron Engine Blocks

Chevrolet Performance Bowtie big block Chevy cast iron engine blocks are CNC-machined. The race-prepared blocks feature blind head and accessory mounting bolt holes, a deck configuration that enables the use of any big block Chevy cylinder head—and cylinder bores that may be safely bored to a 4.600 in. maximum diameter, while maintaining a .250 in. minimum cylinder wall thickness. These engine blocks differ from the production-machined Bowtie versions in certain areas; they start from raw castings and are not "conversions." They also use a rear seal adapter to convert the Gen V/VI one-piece rear main seal to a Mark IV type 2-piece seal that facilitates the use of a widely available Mark IV style crankshaft. The intermediate caps also feature 16 splayed outer bolts, which anchor the caps into the strongest section of the blocks and prevent bearing cap movement under high loads. The main oil gallery on these blocks is relocated and enlarged to a 9/16 in. diameter to allow increased oil flow through the block. These Bowtie blocks have inner head bolt bosses, which allow for better retention of the cylinder heads in high-horsepower applications when the cylinder heads "lift" from the blocks due to high cylinder pressures. Order the style and deck height preferred for your application.

Chevrolet Performance Rectangular Port Dual-Plane Intake Manifolds

Chevrolet Performance rectangular port dual-plane intake manifolds are for those who honor the tradition that states: If you're going to make power with a big block Chevy, you have to use rectangular port heads. These intakes have two separate plenums which accept air/fuel from the carburetor—ensuring less overlap between induction pulses. The result is a cleaner pulse, particularly at low rpm. Chevrolet Performance manifolds are constructed to deliver superlative airflow and horsepower, and can be used with high performance aluminum or cast iron heads.

Chevrolet Performance Bowtie Aluminum Cylinder Heads

Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in. (Mark IV) * Use head gasket P/N 12363412 for bores to 4.370 in. and P/N 12363411 for bores 4.470 in. to 4.540 in. (Gen V, VI) * Use head bolt kit P/N 12367779 Bowtie Oval-Port Aluminum Cylinder Head Assembly: * Completely assembled with 2.250 in./1.880 in. 11/32 in. stem valves * 290cc oval intake ports * 110cc exhaust ports * 110cc combustion chambers Cylinder head is assembled with the following components: * 2.190 in. intake valves * Valve spring retainers * 1.880 in. exhaust valves * Valve locks * Valve springs * Valve seals * Valve spring shims * Rocker arm studs * Pushrod guideplates
