Mr. Gasket – Hei Advance Curve Kit (Part No.929G)

Hei Advance Curve Kit

from

$16.49
One of the best, and sometimes missed tuning tricks is not to just optimize your initial timing, but to bring in timing advance more quickly than the stock distributor can allow. Bringing timing more quickly than stock can provide substantial increases in both torque and horsepower depending on your combination.This is done by changing the springs under the cap. This kit includes three sets of springs which can be used in different combinations to provide full advance sooner than stock. Use lighter springs to bring the advance more quickly, and heavier springs to bring it in more slowly. Two new weights with nylon bushings are also included as are instructions to help with installation. Springs are color code as follows: Light Springs – Black Medium Springs – Silver Heavy Springs – Gold

Product Features:
  • Brings in timing more quickly than stock for more torque and horsepower
  • Includes three sets of springs to allow for a wider range of custom tuning
  • Instructions included to help with installation

MSD Ignition – Blaster 2 Coil: High Performance Ignition Upgrade (Part No.8202)

Blaster 2 Coil: High Performance Ignition Upgrade

from

$49.99
If you are looking to upgrade your stock coil, or want to compliment the performance of your MSD blaster ignition, MSD 5, 6 or 7, the blaster coil line is the right choice. All of the blaster coils are designed for improved spark output. Special 100:1 windings are used to provide maximum build-up of voltage. These windings are held secure and kept cool in an oil filled metal canister. 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. There are several versions of the blaster coil available. All of them have the same internal specifications, but have different housings or components. Each blaster coil can be used with a stock ignition, blaster ignition, MSD 5, 6 or 7 ignition control. 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.

Product Features:
  • Improved output coil for electronic ignitions
  • Works w/Blaster Ignition Or MSD 5/6/7 Series
  • Ballast Resistor Required If Used w/Stock Points Ignition
  • Alkyd tower w/high dielectric properties lessens carbon tracking
