MSD 85551 Chevy Billet Distributor

• The housing is machined from a billet of 6061-T6 aluminum on a state-of-the-art CNC machine producing exact tolerances
• For high rpm stability, a .500” steel shaft is supported by a sealed ball bearing and a long sintered bushing
• This shaft also receives a QPQ coating for friction reduction and resistance to corrosion
• A precision machined reluctor is attached to the shaft which triggers the magnetic pick-up mounted in the housing
• This high output magnetic pick-up is the most accurate way to trigger your ignition
• Plus, with no moving parts to wear or adjust, the pick-up is maintenance free
• Just above the pick-up is MSD’s adjustable mechanical advance assembly
  • Different springs and stop bushings are supplied so you can tune an advance curve to match your application
• Fits Small Block or Big Block Chevy V8
• Cap has HEI-style terminals
• Iron distributor gear

 

MSD 6425 6AL Digital Ignition Control Box

• Features a higher output with 530 primary volts and 135mJ of spark energy
• Efficient components use less current to produce more power
• Set an rpm limit on the MSD 6AL rev limiter with two rotary dials
• Has the same bolt pattern as the original 6AL, but with a lower profile housing
• Built-in LED for system checks
• All wires exit the same side through a locked, sealed connector
• Compatible with 4, 6 and 8-cylinder engines

MSD 8202 Blaster 2 Ignition Coil

• Special 100:1 windings, kept cool in an oil filled metal canister, are used to provide maximum build-up of voltage
• The tower assembly is molded of durable alkyd material due to its high dielectric characteristics while wide spaced brass primary terminals prevent the possibility of spark
• Can be used with a stock ignition, Blaster Ignition, or MSD 5, 6 or 7 Ignition Control
• For use with stock or MSD electronic ignitions
• Most late model vehicles with electronic ignitions do not require a ballast resistor, check your ignition and manufacturers specifications to determine if a ballast is required in your application
• Improved output coil for stock points or electronic ignitions, Blaster Ignition, or MSD 5, 6, and 7 Series (ballast resistor required for points)
• MSD Red metal canister is filled with a premium grade oil for cooling
• CARB E.O. Approved
• Turns ratio:  100:1  
• Primary resistance:  .7 OHMs  
• Secondary resistance:  4.5K OHMs  
• Inductance:  8 mH  
• Maximum voltage:  45,000 Volts  
• Peak current:  140 mA  
• Spark duration:  350 uS 
• For use with stock or MSD electronic

 

MSD 8213 Coil Bracket

• Offers easy, univer­sal mounting for standard size ignition coils up to 2-1/4" in diameter
• Uses a bolt and nut combination instead of the easily stripped self-tapping screw common on other brand brackets
• Perfect for canister type coils
• Adjustable from 1-3/4" to 2-3/8" with slight bending of mounting tabs

 

MSD 31229 Super Conductor Plug Wires, 8 Cyl 90 Deg Plug, 90 Deg Plug

• Engineered from the inside out, the 8.5 offers everything you have everwanted 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 its 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) "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
