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.

Coker Classic Star Series Whitewall Tires
Coker Classic Star Series Whitewall tires are modern radials with best-in-class speed, load and traction ratings. They feature stylish whitewalls, which are built into the tires from Day One—delivering the perfect look for your classic car. The whitewalls fit many American and European classic cars from the 1960 and earlier. Star Series tire ratings help them to provide excellent treadwear, traction, and temperature control. Another best-in-class rating is the T speed rating (118 mph), as well as XL load rating, thanks to a reinforced sidewall. The low-noise tread looks and performs nicely; and these tires are DOT approved and E-marked for the European market. You won't find a better whitewall radial tire on the market! * Best-in-class traction: Star Series tires feature Grade-A traction and temperature ratings, meaning you can expect excellent handling and traction on wet and dry roads. They're engineered to outperform all other whitewall tires, and feature a 480 AA UTQG rating for long-lasting tread life and unbeatable traction. This makes your classic car safer to drive in all weather conditions and improves your driving experience. * Star Series tires are engineered with a reinforced sidewall to better support the weight of classic cars. This reinforcement gives the tire Extra Load (XL) rating, meaning added safety and a long-lasting sidewall that won't break down over time. * Star Series tires feature a genuine wide whitewall sidewall style. This means that the bright white rubber is added directly to the tire sidewall during initial construction of the carcass, resulting in a truly integrated, high-quality product after vulcanization. Wide whitewall tires were a very popular choice from the 1930s through the end of the 1950s, and were eventually phased out of mainstream production by 1962. Originally, wide whitewall tires featured a bias ply construction, but now Coker Tire offers them in original style bias ply and modern radial construction. * T Speed rated: Up to 118 mph (190 km/h). Often required OE for higher performance trim level classic automobiles. * Available in a wide range of sizes

COMP Cams High Energy Hydraulic Lifters
These High Energy hydraulic lifters from COMP Cams feature a patented, constant orifice-metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and the precisely coined bottom surface of the pushrod seat is maintained throughout the engine's rpm range, eliminating excessive oiling at high speeds. The pushrod seat is made of a special powdered metal iron alloy, heat-treated for strength and wear resistance. The longer piston is produced with through-hardened steel that provides more bearing surface and increased lifter longevity. These lifters have a lightweight check valve disk that allows for quicker response, resulting in increased engine speed before valve float.

Summit Racing™ Headers
Our Summit Performance® headers are manufactured from mandrel-bent tubing for superior flow and greater horsepower. The headers feature a pressure-formed collector for a better flow rate and a JIG-welded tube-to-flange plate for a perfect fit. They're made for off-road and racing use only. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment. The headers are available in a wide range of styles, sizes, and configurations. Order the pair recommended for your application. (Special warning regarding Summit Racing™ painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.)
