The B&M Megashifter has it all, form, function and classic style. This all adds up to bring you a quality shifter that’s been one of the most popular automatic shifters of all time. The light truck Megashifter is better suited for truck and bench seat applications with its overall height of 14.85-inches tall (2.25-inches taller than #80690 Megashifter.) The positive ratcheting action won’t allow you to over-shift and miss a gear at that critical moment, along with the reverse lockout feature meets NHRA/IHRA safety rules for those weekend grudge races at the track, while the look and feel of the T-handle and accordion style shift boot really shows off its racing heritage. Other features include a black console that you can trim to match the contour of your vehicle’s floor, 5-foot long shifter cable, cable brackets, transmission shift levers, chrome plated top plate with lighted gear indicator and everything needed for an easy at home installation. An optional T-handle with a 12-volt button is available separately for actuating a trans-brake, nitrous oxide or other accessories for the hard-core performance enthusiast. This shifter fits most popular Chrysler, Ford and GM 3 and 4-speed automatic transmissions.

The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference. In a single 12 inch length of super conductor wire there is only 40 – 50 ohms of resistance. That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it’s great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) or choke. This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears. Available in universal kits and bulk lengths.

Product Features:

Custom Fit For Make And Model Listed
Wires Are Pre-Cut To Exact Specifications
Bolt-on Performance
Conductor core features DuPont Kevlar material for increased tensile strength

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.

Mallory’s UNILITE (R), and magnetic breaker less ignition modules are self contained module assemblies which have no moving parts to wear out. Using Mallory’s time tested breaker less ignition circuit, combined with modern surface mount thermal-clad construction, these ignition modules can drive both OEM and high performance ignition coils. For best results always use a Mallory PROMASTER coil or a Mallory chrome electronic ignition coil. These are also an excellent choice for triggering one of the Mallory HyFire series of electronic ignition controls. Hookup is as easy as a three wire connection.

Engineered for faster rise time, longer spark duration and increased performance. Unique design with premium grade wire, special low resistance, high turns ratio windings. Produces higher spark energy with breakerless electronic ignition systems. For points application the supplied 0.85 ohm ballast resistor must be used in conjunction with the vehicle original ballast resistor, if so equipped. Oversized molded case with integral cooling fins and high capacity oil filled construction provide high thermal conductivity ensuring cool operation and long life. Extra tall tan Alkyd tower and integral voltage dam eliminate “flashover” to primary terminals. Comes complete with mounting hardware and 0.85 ohm ballast resistor. Effective up to 6,500 RPM.

Multi-Layered Steel (MLS) exhaust gaskets are designed for extreme cylinder pressures produced by high horsepower high compression turbo-charged, supercharged and nitrous oxide injected engines. Manufactured from three stainless steel layers, they resist corrosion, will not burn through or push out and maintain maximum fastener torque retention. Stress formed inner and outer layer embossments act like springs that rebound under exhaust flange clamp load, creating force to seal extreme exhaust pressures. Total gasket thickness .075 inch. Will not deteriorate from scrubbing action caused by different expansion rates in aluminum and steel materials.
