Flying Magnet Crank TriggerSmall Block Ford 289-302-351W, with 6.562" Harmonic Balancer, Red Anodised Billet Aluminium
Brand: MSD
Part Number: MSD8640
Description:
  • Absolutely the most accurate way to trigger the ignition.
  • The non-magnetic pickup cannot be false triggered.
  • Powerful magnets are embedded in a billet aluminium trigger wheel.
  • Kits feature special brackets and mounting hardware for a variety of engines.

For a long time, racers have known that one of the best things to do to an engine to improve its performance is to stabilise the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminium wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle.
Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be her bolts, debris or even vibrations which will cause a loss of power or engine damage. The MSD Flying Magnet Crank Trigger uses four magnets secured in the aluminium 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 CNC-machined aluminium bracket securely holds the pick-up in place and is slotted to provide a wide range of timing adjustment. Spacers are included so you can mount the bracket on engines with standard motor mounts or engines with a .25" motor plate. These systems will trigger MSD 6, 7, 8 and 10 Series Ignitions and all MSD Timing Accessories.

Comfort!
Size: One Size, Color: (100) White / White / Halo Gray
Very comfortable! Thinner than the picture shows, but I like the fact that they are no show but still higher in the back and front to protect my heels and such.

Sizing way off
Size: One Size, Color: (100) White / White / Halo Gray
These were my favorite socks, at least the old style was. They redid them and I was okay with it. However, I don't understand how they are a one size fits most. I tried them on and they were still too big at the top. There was so much extra fabric at the toes. For reference, I wear a size 8.5 women's shoe, typically. The packaging says fits most from size 5.5 to 12. I don't understand how it fits that wide range of shoe size. Definitely returning these and I will be buying something else.
