NMRA Adds Coyote Modified Class
Coyote Modified will be NMRA’s newest heads-up drag racing category in 2014, and it picks up where the previously launched Coyote Stock leaves off.

"Last year we launched the first-ever sealed crate engine program in drag racing history with the popular Strange Engineering Coyote Stock," explained NMRA Tech Director Dave Werremeyer. Coyote Stock has seen its naturally aspirated, crate-powered Mustangs run deep into the 10s.

Coyote Modified is a heads-up eliminator with few barriers to entry—the power adders will likely dictate the mechanical limits instead of a long list of specs. The idea behind this is that this relatively loose formula will generate a wide range of competitors that can enter, which can include everything from street cars to purpose-built racecars. The official Preliminary Rules are listed below and interested parties are invited to contact the NMRA at NMRARules@promediapub.com with any questions. While Coyote Stock has been primarily dominated by late-model Mustangs, the rules for both classes allow for any year and any model of Ford vehicle. If you’re planning on competing in one of these classes with a vintage Ford, we want to ear from you. Contact us at modified.mustangs@sorc.com.


Tuning Your Holley
Many enthusiasts’ first modification on acquiring a car destined for performance was to swap out the factory induction system for a new Holley four-barrel carb and intake manifold.

While many of today’s modern cars have moved past carburetors and into high-tech fuel-injection systems, most cars from the highly collectible eras are still running carburetors. Carbs are comparatively inexpensive, highly tunable, and do not require laptops, expensive tuning equipment, or computers to function. And by far the most popular carb still in use is the Holley carb.

In David Vizard’s Holley Carburetors: How to Super Tune and Modify, the best-selling author explains the science, the function, and most importantly, the tuning expertise required to get your Holley carburetor to perform its best for your performance application, whether it’s street, ’strip, supercharging, or race applications. Holley has been a best-selling subject for years, and this much-needed update guides you through the traditional 4150 Double Pumper, Dominator, and 4160 vacuum secondary models, as well as all the recent releases from Holley, including the Ultra Street Avenger and Ultra HP Series Carbs.

With its high degree of tuning ease, and with all the new models coming into the market, the knowledge of an expert like Vizard is a requirement to meet your performance goals, now more than ever. This book is an essential addition to any hot rodder’s library.
