Summit Racing™ TH400 Transmission Cases
Summit Racing™ TH400 transmission cases are a street/strip version of the TH400 aftermarket SFI transmission case. The bellhousing is not included and must be purchased separately. A direct replacement for the GM case, Summit Racing™ cases use a permanent mold casting to increase the case wall thickness, making it sufficient to pass SFI 4.1 certifications without the need for any external shields or internal liners. The 2-piece design allows them to be used with all popular engines by simply changing bolt-on bellhousings. Features include: * Speedometer and governor provisions * Longer band anchor pins captured by oversize bosses * Multiple external pressure taps allow for monitoring of circuit pressures * Accepts all style oil pumps, including 8-bolt and vari-pitch designs * Heli-coiled bellhousing and oil pump threads * Pre-machined to fit larger custom planetary gear carriers

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.
