Overview
Upgrading to an MSD Flying Magnet Crank Trigger Kit will deliver the precise and reliable signal that a high performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system / ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see below list for recommendations), you'll be able to adjust timing in the precise increments required for your engine. Coyote 556-173 We recommend using ATI 918047-MSD but will also work with 918047N and 918047NA LS 8 inch 556-174 Designed to work directly with ATI 917302, 918852, 917264 or 917242 LS 7.28 inch 556-175 Designed to work directly with ATI 917777, 917211 or 917234 LS 6.56 inch 556-176 Designed to work directly with ATI 917776 or 917215

Love this color brown! Very nice shirt!
Size: XX-Large, Color: Brown, Size: XX-Large, Color: Brown
Purchased for my husband for a fall wedding! The fit was great and it was wrinkle resistant. The material was soft and comfortable. It was warm enough for a fall wedding but also breathable and he looked amazing in it! I LOVE the color!

Vary comfortable
Size: X-Large, Color: Brown
I really like these shirts. I got one
in the brown color because I didn't have a nice brown shirt. They fit so well and they have a very smooth feel, almost like silk. My wife said that I look great and that's what matters most. She also likes the fact that they are wrinkle free so there's less ironing. 😃
I now have five different colors, and they all fit perfectly, and I love the way they look and feel. Thank you

Great Color Dress shirt
Size: Medium, Color: Light Green
I purchased this dress shirt for my husband when he needed something to wear as a wedding guest. My dress had a bit of turquoise in it so we thought this would be a good compliment to what I was wearing. We ordered his normal dress shirt size and this was a perfect fit.My husband is slim and it was nice that this shirt wasn't boxy at all. The neck was a comfortable size and the arm length was spot on. He has nicer, more expensive dress shirts of better quality but this seemed to work out just fine for what we needed. The color was a nice shade of turquoise.. not too green and not too blue so we lucked out in that area also. We did wash this before wearing. My husband didn't complain about any stiffness/scratchiness etc.the whole day! I would say anyone wanting to purchase this shirt, that they will be pretty happy with the overall fit and comfort.

A dress shirt that allows for needed length.
Size: X-Large, Color: Light Green
Very nice dress shirt for a reasonable price, and for a size XL, the sleeves are actually long enough. The fit is relaxed and looked very professional, with a tie if one is appropriate.
