MSD Ignition – Trigger Wheel; Flying Magnet; Small Block Chevy (Part No.8611)

Trigger Wheel; Flying Magnet; Small Block Chevy

from

$290.99
For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilize the ignition timing. The MSD flying magnet crank trigger system does exactly that by using magnets embedded in an aluminum wheel. The MSD flying magnet crank trigger uses four magnets secured in the aluminum trigger wheel that pass by a stationary non-magnetic pick-up to trigger the ignition. This flying magnet design produces accurate trigger signals and the non-magnetic pick-up cannot be false triggered. Each flying magnet crank trigger includes a two-piece mounting bracket for the non-magnetic pick-up that in most cases will work on either the passenger side or driver’s side of the engine (the SB Chrysler and SB Ford brackets mount on only one side). The adjustable bracket provides a wide range of timing adjustment and spacers are included. These systems will trigger MSD 6, 7, 8 and 10 series ignitions and all MSD timing accessories.

Product Features:
  • Replacement crank trigger wheel for small block Chevy
  • Absolutely the most accurate way to trigger the ignition
  • The non-magnetic pickup cannot be false triggered
  • Powerful magnets are embedded in a billet aluminum trigger wheel

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 – Wire Set; Super Conductor; Small Block Chevy with L.P. Distributor (Part No.31249)

Wire Set; Super Conductor; Small Block Chevy with L.P. Distributor

from

$126.99
The MSD 8.5mm super conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted 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 it’s 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) or 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. Available in universal kits and bulk lengths.

Product Features:
  • Less than 50 ohms per foot for superior spark
  • Ferro-magnetic impregnated core creates an effective EMI choke
  • 40 ft. Of Conductor Wound Into A Single Foot Of Wire
  • For high EMI suppression
  • Conductor core features Dupont Kevlar material
  • Proprietary compound sleeves for resistance to high heat/abrasion
