Gary Windsor Shifting Gears For NMRA Factory Stock

Posted By: Steve Baur
The competition in the NMRA’s Richmond Gear Factory Stock class is as tough as a heads-up category gets, and FS racer Gary Windsor and car owner Michael Washington have put some major changes/upgrades into the gray notchback over the winter for the 2022 racing season.
The Fox-body Mustang, owned by JDM Engineering Limited Street racer and stick shift bandit Michael Washington, and nick named “Somewhat Evil,” originally received a sealed Gen II Coyote engine and was upgraded with a 2018 intake manifold for Factory Stock battle.
“There was a year or two when the stock engine was competitive, but the class has evolved from that,” said driver Gary Windsor.
For the 2022 season, the team has switched to a Gen I powerplant built by RGR Engines, which built Washington’s Pure Evil, full-tilt Coyote engine for the Limited Street class.
“We took it to local track for test pass with the automatic and the new engine and it ran the fastest it ever has,” Windsor revealed.

In addition to the new engine, Windsor and Washington decided to make additional upgrades that included a new Team Z 9-inch rearend with a Dewco differential and Strange Engineering gun-drilled axles. Strange Engineering disc brakes were bolted on and lastly, the due decided to drop in a G-Force Racing Transmissions G101a four-speed manual transmission.
“We had originally switched the transmission leading up to Bradenton, but in the middle of that, we found out the rear housing wouldn’t work, so we put the 8.8 and the C4 back in it,” Windsor explained. “It still had World Cup tune in it and we couldn’t reflash it. Then the tongue jack broke on the trailer. It’s always a mad thrash every year to start the season, but North Carolina seemed a lot closer,” the Pasadena, Maryland, resident said of his decision to abort the trip to Florida for the 2022 Holley NMRA Ford Nationals season opener.
Now, the race is on to make the next event, the Scoggin Dickey Parts Center NMRA/NMCA All-Star Nationals presented by MAHLE Motorsport at Rockingham Dragway.
“We need to put the transmission back in, cut the hole for the shifter, then tune the car. And we have to figure out where to add the required 300 lbs. for the stick shift. The new engine is a Gen 1, so save 75 lbs for that combination,” Windsor told us. “Shawn at Proformance Transmissions has been a vital part of what we do, and he’s updating the automatic. We might switch between the two throughout the season as needed.”
With Windsor and Washington having met while both of them raced under the JPC Racing banner, it’s no surprise that former JPC driver Ryan Hecox will be helping them out with the clutch setup as the team wraps their heads around the new drivetrain combination.
