“This Beehive Valve Spring Kit for LS engines is designed for hydraulic roller cams and includes carefully matched Beehive Springs, steel retainers, locks, seals and spring seats. With a .625″” maximum lift, these Beehive Valve Springs deliver increased valve train stability and a much lighter valve train. This is achieved with less spring pressure for better valve control and reduced weight of both the spring and retainer. The unique Beehive shape handles valve train stress more efficiently to eliminate damaging harmonics and increases high RPM horsepower and durability. The oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valve train stress more efficiently and allow better heat dissipation for longer life.Kit Includes:26918-16 Beehive Valve Springs774-16 Steel Retainers623-16 7° Steel Valve Locks511-16 Valve Seals4705-16 Spring Seats”

Edelbrock – Edelbrock Performer-Link Adjustable True-Roller Timing Chain Set, 7812 (Part No.7812)

Edelbrock Performer-Link Adjustable True-Roller Timing Chain Set, 7812

from

$83.99
Edelbrock part No: 7812 Performer-Link timing chain is for use with Edelbrock or stock cams. They have a solid-bushing chain for a true bearing surface that rolls with the sprockets, eliminating chain stretch. Cam sprockets are made from 35,000 psi tensile strength cast iron. Crank sprockets are made from billet SAE-1144 steel and induction heat treated. Four Performer-Link sets are stock replacement parts and 50-state legal (see listings in bold type). All other sets have three keyway setting points to ensure accurate timing selection for early or late-model vehicles. Performer-Link timing sets are not for use above 6500 rpm. Performer roller chain sets are engineered to operate up to 6500 rpm. Never hammer directly on chain or sprockets. You can crack the hardened links and pins and cause early failures. Use a sleeve for installations that require hammering, a brass drift punch may be used if you carefully alternate blows on either side of the sprocket to avoid cocking. Never stretch the chain with a screwdriver. Check for clearance between the timing chain and block and between the chain and front cover before reassembly. Be sure that both cam and crank sprockets are exactly in line with each other. Misalignment can cause chain to break.

Competition Cams – Competition Cams Valve Seals, 503-16 (Part No.503-16)

Competition Cams Valve Seals, 503-16

from

$223.99
COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Edelbrock – Edelbrock Intake Manifold Gasket, 7280 (Part No.7280)

from

$30.99
Edelbrock part No: 7280 Intake Gaskets for 1961-79 3626-389-400-421-428-455 Pontiac engines allow for optimum flow and performance. Any gasket can create a seal, but a good gasket can do it with less clamping force, and for a longer period of time. The new MP-2N Micropore technology does not use solvents making our gaskets environmentally friendly. Impervious to most chemicals, this synthetic fiber composite provides a high recovery under load. This means that when compressed, the gasket will conform to any imperfections on the sealing surface even using lower flange pressures. A nitrile bead around each port opening makes the seal even better.

B & M – B & M Tork Master 2400, 20404 (Part No.20404)

B & M Tork Master 2400, 20404

from

$399.99
The Tork Master 2400 fits 1965-91 GM TH400, 425, 375 and 1968-81 GM TH350, 375B (not 350C.) Don’t let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features, making them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications.

B & M – B & M Holeshot 3000, 70442 (Part No.70442)

This converter retains the lock-up feature. Holeshot torque converters are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Tork Master or Traveler series of converters. The Holeshot 3000 converter is an excellent choice for vehicles with some performance engine modifications, particularly big cams that tend to reduce low-end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings. Other features include fully balanced and pressure tested by expert technicians. If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of converters. Notes: Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. This converter is Not recommended for supercharged, plate-type nitrous oxide or trans-brake applications. The product images shown are for illustration purposes only and may not be an exact representation of the product. Will Not fit 1997-05 Corvette. Has both 10.75 and 11.08-inch bolt circles
