A year ago, the SAMTech.edu 91做厙 Factory Stock Showdown produced some of the most thrilling action of the season with former Pro Stock driver Drew Skillman earning the championship over a stacked field that included fellow Pro Stock alumni Bo Butner, as well as current Top Fuel star Leah Pruett. Five different drivers won a least once last season with the Ford Cobra Jet claiming six titles and the COPO Camaros earning two. While the Dodge Challenger Drag Pak teams were shut out of the winners circle, Pruett, the 2108 class champ, scored a runner-up at the season-ending event in Dallas.

Throughout the eight-race season, maintaining parity among each of the three brands was an ongoing process with the NHRA Technical Department issuing multiple rules changes, mostly adjusting minimum weights and supercharger overdrive. In the end, the racing was extremely competitive with the top eight cars rarely separated by more than a tenth of a second. While Skillman and his father, Bill, combined for five wins in six final rounds, the championship wasnt decided until the final weekend of the season.

So, whats ahead for the popular Factory Stock Showdown class? Likely more of the same as teams gear up for the traditional season opener in Gainesville. Ironically, the category that many feel is the new Pro Stock actually is a closer representation of the old Pro Stock class, the pre-1982 Pro Stock that featured differing weight breaks for individual engine and chassis combinations. Reminiscent of the pre-1982 Pro Stock, there were significant rules adjustments made this winter that are sure to affect the overall performance of the Factory Stock class, all of them designed to maintain the balance between brands in the class. With limited testing time before the season opener in Gainesville, its anyones guess which teams or combinations might have the upper hand.

Four-time world champion Kevin Helms remains the crew chief of the Don Schumacher Racing Dodges driven by Pruett and former Pro Stock driver Mark Pawuk. Helms is eagerly awaiting the delivery of the teams new 2020 Drag Pak Challengers but admits that they wont be ready for the Gainesville opener. Instead, hes prepared to do battle with the same cars they finished the 2019 season with. At the Dallas event, Pruett qualified second and reached the final while Pawuk was the No. 9 qualifier.

Weve got a new car coming and the new 3.0-liter supercharger, but we dont have them yet, said Helms. Well be in Gainesville, but obviously, I wish we had the new cars. I dont think well be at the top of the class, but I think we can hold our own. With our combination, and the older blowers were running, were much more sensitive to temperature changes. We tested in Orlando, and it was 83 degrees, so the conditions werent exactly stellar, but you never know what youre going to get in Gainesville. It could be 60 degrees or it could be 90.

As much as anyone, Helms understands the need to maintain parity in the class and the challenges associated with doing so in a class that features a wide variety of body style and engine combinations.

Last year, we [the Dodge teams] didnt get anything, and we had to work all year to catch up, Helms said. This year, we eventually have a new supercharger and a new car, but we still dont know what to expect. We also got a 3.50 [-inch] pulley, so that means I still need to pull out a magic wand and find a 10th, and Im sure that [engine builders] Chris Holbrook, Greg Stanfield, and David Barton didnt sit back all winter and do nothing. Still, this is a fun class, and its still a drivers race. And, you still have to get the car down the track, which is always a challenge on those [9-inch] tires.

As Helms noted, engine builders, including Greg Stanfield, did indeed have a hectic and productive offseason. Stanfield, who won four world championships in Super Stock before launching a successful career in Pro Stock, currently builds engines for a number of successful factory Stock competitors, including 2019 event winners Arthur Kohn and Stephen Bell. Stanfields son, Aaron, is also expected to pull double duty this year in Pro Stock and Factory Stock, and Chris Garner has partnered with Kohn to expand the Sanfield team to four cars.

Four cars is enough, Stanfield laughed. To be honest, I dont do a lot [of development] anymore. Thats all Aaron and his guys in the shop. Theyve got a couple of kids from the SAMTech program, and theyre very good. They work extremely hard, and Im mostly there as a security blanket if they get stuck on something.

Last year was a watershed year for the Factory Stock class in terms of performance. New rules combined with advancement in supercharger technology caused elapsed times to plummet deep into the seven-second zone. Drew Skillman made the quickest pass of the year with a 7.71, and a number of Factory Stock racers topped 180 mph. Those numbers likely wont be challenged this season since current rules have dialed power levels back a bit. Regardless, seven-second runs should be the norm, and Factory Stock teams are still faced with the difficult challenge of applying approximately 1,400 hp to a 9-inch wide rear tire. Stanfields engines appeared in five finals last year, including Bells win against Kohn in the all-COPO Camaro final in Topeka. He predicts another extremely competitive season.

This year, Im hoping we have another good season. We finished No. 2 in the last two years, and now, we need to close it out, said Stanfield. I like this [Factory Stock] deal because its not like Pro Stock where every car is the same, and its all about who can make the most horsepower. Factory Stock requires a lot more finesse, and there are a lot of areas to work in. Lets face it, the people who have money will always spend it, but if you have a brain and the ability to work hard, you dont necessarily need money. I preach that to Aaron all the time. If youre willing to put in the work, youll be successful.
