The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility spark. Uses a bolt and nut combination instead of the easily stripped self-tapping screw common on other brand brackets. The low resistance results in less loss spark energy so more reaches the plug. This pickup is extremely accurate and never requires adjustment.
CNC machined billet aluminum housing and base. Perfect for canister type coils. The outer sleeve that surrounds the conductor assembly is just as impressive A proprietary blend of silicone and synthetic material produce a highly resistant to high heat well abrasion tears. Special oil tract improves lubrication to the distributor and cam gear.
That is the lowest resistance of any helical wound wire. Adjustable slip collar mounting flange for engines with modified deck height . Maintenance-free magnetic pickup and precision rector create stable trigger signals throughout the rpm range. The conductor is wound extremely tight around a special core.
Headquarters. Will not accept a vacuum advance canister. Part # 9109190 Condition New Brand MSD Sold Kit Details Info Breathe new life into your Small Block Chevy or Big engine with this easy-to-install distributor ignition kit. This strong, billet aluminum distributor is set up for engines that run locked-out timing or an MSD Timing Computer.
Kit Includes: 1 MSD 85501 Chevy V8 Pro-Billet Distributor, Locked-Out Timing. With no advance assembly, the rotor plate is welded directly to oversized shaft. Polished steel shaft is QPQ coated and guided by a sealed ball bearing. Locked-out Timing from the factory.
Supplied with an HEI distributor cap and rotor accepts Cap-A-Adapts. Since this distributor is designed primarily for race engines, an oversized .006 bronze gear installed along with adjustable slip collar modified blocks, heads or intake manifolds. O-ring seals can be added to modified blocks improve oil pressure control. Adjustable slip collar allows you to adjust the distributors height - great for engines with modified intakes and deck height .
Designed primarily for race applications with no mechanical advance. Built-in LED for system checks. This choke, or suppression capability, keeps the EMI inside wire where it cannot interfere with other electronics on your vehicle. For use with stock or MSD electronic ignitions.
All wires exit the same side through a locked, sealed connector. A sealed ball bearing guides the top of shaft while an extra long sauntered bushing stabilizes lower portion. Trigger signals are produced via a high-output magnetic pick-up. Efficient components use less current to produce more power.
