MSD 8.5mm Super Conductor Spark Plug Wire Sets
MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications, assembled or not, with a variety of terminal and boot end options.

MSD Pro-Billet Ready-to-Run Distributors
MSD Pro-Billet Ready-to-Run distributors are the perfect upgrade for weak OE electronic distributors, outdated points distributors, and large HEIs or DuraSparks. All that's required is to install the distributor in the engine, and connect three wires and the coil! A maintenance-free magnetic pickup accurately triggers this ignition with increased output from the amplifier, easily outperforming stock ignitions. It will smooth out the engine's idle, improve starting, and perform at a much higher rpm. The housing is machined from billet 6061-T6 aluminum, using state-of-the-art CNC mills and lathes for a unit with no porosity or weak areas. For stability and endurance, an oversized steel shaft spins in a top-mounted sealed ball bearing, while an extra-long sintered bushing guides the shaft at the base of the housing. This shaft also receives a QPQ coating for low friction wear and resistance against corrosion from humidity and ozone buildup. The distributors feature MSD's adjustable mechanical advance, which allows you to custom-tailor an ignition curve to match your engine's needs. Most models are also available with a vacuum advance canister to help improve economy. Order the model recommended for your vehicle and engine application.

MSD Pro-Billet Locked-Out Distributors
MSD Pro-Billet locked-out distributors are built from strong billet aluminum for engines that run locked-out timing or an MSD timing computer. With no advance assembly, the rotor plate is welded directly to the oversized shaft. A sealed ball bearing guides the top of the shaft, while an extra-long sintered bushing stabilizes the lower portion. This extra support ensures stable and accurate timing signals throughout your engine's entire rpm range. Trigger signals are produced via a high-output magnetic pickup. This pickup is extremely accurate and never requires adjustment. A precision-manufactured reluctor is responsible for triggering the pickup. Since these distributors are designed primarily for race engines, an oversized (+.006 in.) bronze gear is installed, along with an adjustable slip collar for modified blocks, heads, or intake manifolds.

MSD Pro-Billet HEI Distributors
The MSD Pro-Billet HEI distributors pick up where the originals left off. Drawing on years of high-performance ignition experience, MSD engineers created a unique ignition module and internal coil that are capable of running above 9,000 rpm. Stock and other aftermarket modules lose spark energy at about 4,500 rpm. These modules produce 50 percent more current than stock units, and deliver a much more precise timing signal as well as more dwell control. The coil delivers over 100 millijoules of energy across the plug gap. For strength and high rpm stability, the QPQ-treated oversized shaft is guided by a sealed ball bearing on top and long sintered bushing at the bottom. The QPQ coating provides a low-friction coating on the shaft and also makes it highly resistant to corrosion. TIG welded to the top of the shaft is an adjustable mechanical advance assembly. The distributors are supplied with extra springs and stop bushings, so you can tailor an ignition curve to match your driving needs. The advance assembly features chromoly weights that slide on nylon pads for smooth timing advancement through the entire rpm range. There is also a vacuum advance canister to improve economy while cruising. All of these features are enclosed in a great looking, billet aluminum housing that is CNC-machined for accuracy and incredible strength. The distributors come complete and ready to drop in with a high-quality rotor and cap with brass terminals for great spark transfer. Simply connect a 12 V source to the distributor and you're up and running. They're designed to replace GM HEI distributors that use a 4-pin ignition module.

Lakewood Safety Bellhousings
Lakewood safety bellhousings are designed for maximum performance and durability. They are cut on CNC 5 axis laser cutters rather than plasma cutters to improve finish quality, reduce heat damage and warpage from the plasma cutter, improve speed of manufacture, and make them all exactly the same. All bellhousings feature a scalloped plate on the bottom of the transmission surface made from G70 grade steel (70,000) psi which will help eliminate stripping the transmission bolts. The engine plates are made of H60 grade material and the bells are roto-brated after welding to relive any stresses created from the hydro forming, annealing, or welding process prior to machining and painting. The roto-brating process also closes the metal on the outer surface making them stronger. Ever wonder how the SFI tests bellhousings like these Lakewood safety bellhousings? First, they bolt the bellhousing to a machine with a cast iron flywheel and saw inside it. Then they spin the flywheel, causing the saw to cut through it until it explodes. If the bellhousing can contain the explosion, the bellhousing is approved. These safety bellhousings are a safeguard to minimize the destructive effects of such an explosion. Don't take unnecessary chances with your safety and the safety of innocent bystanders--Lakewood not only provides top-notch products, they also provide peace of mind.
