Fel-Pro gaskets are specifically designed for the repair environment to deliver a reliable seal on even the most troublesome applications. Designed for imperfect sealing surfaces and manufactured with proprietary materials, you can count on Fel-Pro for innovative sealing solutions for the real-world repair environment.

Fel-Pro Performance Gaskets deliver reliable sealing under grueling racing conditions.

The Edelbrock No: 7380 head gaskets provide the best sealing solution and are matched to Edelbrock cylinder heads for optimal performance. Edelbrock relies on industry leading head gasket manufactures to ensure our head gasket sets will provide the best fit and sealing properties when used with Edelbrock aluminum cylinder heads. Edelbrock head gaskets are manufactured from high-density materials and feature a superior design that performs under pressure and provides a long-lasting seal, without re-torqueing.

Mr. Gasket Ultra-Seal Head Gaskets are a five layer (graphite core/perforated steel outer layers) composite construction. The graphite core has excellent thermoconductivity (transfers heat) away from hot spots in head preventing gasket burn-out. They provide excellent stability, compressibility and high temperature endurance. A high temperature silicone coating ensures sealing of engine fluids. Compatible with cast iron or aluminum heads, they will not brinell (indent) aluminum cylinder heads. Suitable for high performance street, drag race and oval track use. Sold individually.brbrGasket Bore 4.190 inch, Compressed thickness 0.038 inch.

Mr. Gasket Steel Shim Cylinder Head Gaskets are for high performance street machines, drag racing and oval track racing. With today’s extreme compression ratios you need stronger more durable gaskets. Mr. Gasket steel shim gaskets are made from .020 inch steel shim stock which is thinner than most composite gaskets increasing engine compression. Stress formed embossments will seal the extreme cylinder pressure.

SMALL BLOCK CHEVY HYDRAULIC CAM AND LIFTER KIT – Xtreme Energy: Pro Street/bracket, needs good intake, headers, gear and 3300+ stall.

SMALL BLOCK CHEVY HYDRAULIC CAM AND LIFTER KIT – Thumpr : High performance street, stock converter ok, best with 2000+ converter and gears. Choppy/thumping idle.

“Edelbrock part No: 7162 Performer RPM Camshaft is designed for big-block Chevy 396-427-454 V-8 applications. This Edelbrock cam kit produced 540 HP & 530 ft-lbs. of torque when used with No: 7163 intake and No: 60559 cylinder heads on a 454 engine. The camshaft works well with high-performance’s street applications, Performer RPM cams provide power from 1500 to 6500 rpm. This hydraulic lifter camshaft is dyno-matched to Performer RPM manifolds for high-rpm horsepower while still maintaining acceptable low-end torque. With 10 to 12 inches of manifold vacuum at idle, Performer RPM cams have more lift and duration than most street camshafts. Hydraulic flat tappet lifters are included with each Performer RPM camshaft. Camshaft Specifications: – Duration at .050 Intake: 240 degrees – Duration at .050 Exhaust: 246 degrees – Lift at Valve Intake: .560″” – Lift at Valve Exhaust: .573″” – Lobe Separation: 112 Degrees – Intake Centerline: 110 Degrees – Idle Vacuum at 1000 RPM’s: 10″””

Designed to deliver an aggressive, hard-hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods.

The newest cam technology is used in COMP Cams Xtreme Energy camshafts to deliver optimal performance. There is an Xtreme Energy cam for every use, including off-roading, towing, and street performance. These cams outperform comparable cams from other manufacturers in terms of throttle responsiveness and top-end horsepower because to their aggressive lobe profile, which also increases engine vacuum. There are hundreds of versions that can be installed on cars made between 1955 and the present. Choose the cam made specifically for your use case.

HYDRAULIC – Magnum: Street/strip applications. 10:1+ compression, 3000+ stall or 4 speed. 4.10 or lower gears and aftermarket intake. Very rough idle. OR Oval Track: Good for hobby stock in 454 where hydraulic lifters must be used.

BIG BLOCK CHEVY HYDRAULIC CAM AND LIFTER KIT – Xtreme Energy: Good for street machines, slightly rough idle, stock converter will work but best with 1800+ stall.

BIG BLOCK CHEVY HYDRAULIC CAM AND LIFTER KIT – Xtreme Energy: Strong torque. Excellent response, heavy towing in 454 with 4.10 gear.
