Stamina is a big part of drag racing, just ask Pro Stock winner Dallas Glenn, who needed a hefty dose of it Sunday at the In-N-Out dragstrip in Pomona, Ca., to pick up his fifth career Pro Stock win, and did it at the Lucas Oil NHRA Winternationals.

Glenn walked the drag racing equivalent of the gauntlet to win the race and assume the point lead.

"It's obviously a great long day," Glenn said. "Anytime I'm wore out at the end of the day, I'm pretty happy about it. I mean, I've got an absolutely great car right now. We are just making small tweaks to it, and it's just running really, really good. Really happy with it. It's a different car from last year and I really like it. I'm real comfortable in it, feel real good."

Glenn started from the fourth qualifying position, stopping Chris McGaha in the first round, then took down Bo Butner and No. 1 qualifier and Phoenix winner Camrie Caruso before stopping the most dominant driver through most of eliminations, Matt Hartford.

"Started off, just made a nice clean run," Glenn said. "Second round comes up, and it's another nice clean run. And I think Bo shook and I'm just clicking them off, just making nice clean passes, hitting my shifts.

And then come up against Camrie, and I know she absolutely really wants to beat me. So then she was double O on me last time. I knew she was going to be good and I knew she's fast; she's No. 1 qualifier. So I just did everything I could to absolutely murder the tree best I could. And when it dropped green, it was really happy because it felt really good. And then it took a hard left on me, and then I didn't know if I was going to get it back until about the third gear. And it came back real nice and I ran through the gears. Then I took a glance over and I couldn't see her. So I was pretty thankful about that.

"Then, in the final, I feel like I got pretty lucky that Rob Downing and Dave Connolly and Nate Van Watson Hove gave me a really, really good car for the final round. All went nice and straight; I had a great 60-foot and hit all my shifts good. And it was spinning a little bit through the lights, but we were good enough to hold onto the win. I don't think Matt made quite the run that he wanted and he was really good on the tree. So I was a little nervous when I left on that one because I didn't feel like I got it all.

Glenn's win measured a .003 margin of victory, and that tight tale of the tape put him in the points lead for the first time in his relatively short driving career.

"That feels really good, and obviously, it's early in the season, but points at the beginning of the season mean just as much as the points near the end of the season," Glenn said. "So it feels really good. I'm probably going to take a screenshot of that when the points come out just so I can see it and save it. So hopefully, it ends the same at the end of the year.

Winning at the newly rebranded drag strip in Pomona means the world to Glenn.

"I've always really wanted to win here," Glenn said. "I've raced a lot of sportsman [events] here, and I've done pretty good here in sportsman, but I've never been able to just seal the deal. So to do it in Pomona, we come here twice a year, so it's been slightly frustrating to me. When I've got a great car and then all of a sudden it shakes in semis in one year, or it just goes and shakes first round or there's always little things that are going on.

"I knew I've had a really good race car. I feel like it's just been one tiny little thing that's been holding me up all season so far, and it all came together today. And we stayed and tested Monday in Phoenix, and I think we figured out a lot of stuff. So I think it's going to be a really good car for the rest of the season.

The victory marks two in a row for the new KB-Titan merged operation.

"The Whiteleys have been doing a phenomenal job," Glenn said. "Not saying that Ken and Judy Black haven't. They're the absolute greatest owners. They're the nicest people I've ever met, but we've been doing a lot more testing than we have in previous years and they've been working really, really hard. I know that the last year stung really bad, especially for Greg. And we've been working really hard back at the shop.

"A lot of new things coming, so I think we're going to be really good for the rest of the season. And I feel like some of our performance that appears to be; I think maybe the Elite team might have just fallen off just a little bit like we did the previous year. So I'm sure they're going to get it back and the racing's going to get even tougher from here."
