Overview:

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 four magnets embedded in an aluminum 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 triggered by other 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 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 CNC-machined aluminum 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 and 8 Series Ignitions and all MSD Timing Accessories.

    Love this Dress Shirt
    These are my favorite white dress shirts. Unfortunately, not always in stock. Hard to find. Fits comfortably. Easy to wash and almost wrinkle free after each wash. I barely have to iron them. Fabric is thick, not transparent at all but still breathable. Price you pay was set perfectly according to the quality of the fabric.

    Dressy Shirt, Casual Price
    This slim fit Van Heusen has a fair price, but the feel of a fancy shirt. It's lightweight and has a bit of a glossy sheen. Despite all the negative reviews about the cut being too bulky in the middle, this fits me to a T. I'm pretty slim -- at 6' 140# -- and, while slightly generous in shoulder width and sleeve length, the shirt tapers at the waist very nicely. If tail length is the problem, SHIRT STAYS are a cheap, simple solution. Some reviews also complained about wrinkles. Well, DRY CLEAN -- because yeah, if you're tossing a cotton/poly shirt into a washer and dryer, it will get wrinkly. I pressed the shirt off using an IRON without any problem. In fact, this shirt seemed easier to press than others. Great shirt. Good deal.

    Stain Shield Works, But Not Really a Slim Fit Shirt
    Good quality for the price. Impressed with the stain shield which actually prevents sweat/wetness from showing... even in extreme heat. No joke. But this is not a slim fit shirt in my opinion. Too much material at the waist with not a lot of length to be able to assist in tucking it all in. Also, I imagine it's the stain shield, but there is definitely a chemical smell to the shirt that survived a few washings. If you're sensitive to that smell, it could be an issue.
