7:30 p.m. - More comments from Kyle Busch, driver of the No. 18 M&M's Toyota, who won Sunday's Shelby 427:

(On whether he learned anything about himself after struggling last fall) " Not really. I think to probably take the bad days a little easier -- but I hate bad days. I'm still not gonna take ‘em as easy as some should, especially like yesterday. We had a great car and we should have won that race, too. But, you know, Friday I could have thrown my helmet down and stomped away, told the guys ‘great job, look at what we did.' I just went in the hauler and let those guys go to work and do what they do best. I just kind of sat there and cooled off a little bit, watched the rest of practice. Let's see if I could learn anything from watching guys on TV about practice, watching some different lines of what guys were doing in qualifying trim. I went out there and ran a Mark Martin?type line and ended up getting the pole there. That was pretty awesome to be able to do that. These guys made some good calls on what to do to the car to change it.

"But from last fall, yeah, we had some bad races. It's unfortunate we weren' t able to capitalize on our great season into the Chase and run into the Chase the way we wanted to. Hopefully we can build that back up here. I feel we' ve done a great job of doing that since Daytona. We didn't let Daytona haunt us. We went to California, ran a smart race and finished third. We came here, ran a smart race and won the race. We weren't the best car at either place but we were the best car in Daytona, I felt like, and we missed out there. This could have been a 1?3?1 season (of finishes) thus far. It is what it is. All you do now is look ahead to Atlanta this weekend."

7:10 p.m. - Comments from Kyle Busch, driver of the No. 18 M&M's Toyota, who won Sunday's Shelby 427:

(On winning at your hometown track) "This is pretty awesome. It's very special. You never really know how special they can be until you actually get it done and so today was very, very cool. The last 25, 30 laps, I was just as nervous as could be. I wasn't really all that great at hitting my marks (but) I was hitting them good enough, I guess. Fortunately we ran that many caution laps there at the end. That helped, too."

(On how his race unfolded) "We started out, had to go to the back and just methodically thought our way through there and fought our way through there and just worked on everybody one car at a time. We had to work on our car a lot, too. It was really, really loose in the beginning and I wasn't sure if that was all me or if it was all car from getting loose yesterday and wrecking yesterday so I told myself, ‘You better man up and drive this thing or else we're not going to go anywhere.' Fortunately, we stayed on the lead lap the whole day and, again, just kept plugging away at it and kept working on it. There at the end, getting those guys caught on pit road sort of helped us and got them back behind us and got us further forward that we didn't have to race the great cars. I didn't think we were that great, but we were pretty good."

(On kissing the track's finish line during his post-race celebration) "I kissed the ground that this place was built on. Again, we watched it being built from the ground up. When we were racing out at the Bullring, this was nothing but a dirt lot -- this was actually part of the parking lot, I think, for that Bullring racetrack, so it's come a long ways. I remember sitting up in the grandstands when I was younger and when Kurt and my dad were racing, turning around and looking out there and watching it. They broke ground, I think, in '95 or '96 or something like that. I just kept turning around and watching it, watched the grandstands go up, the banking being put in, the outside retaining wall, the garages being built and stuff. Every weekend we were over at the Bullring and saw what was happening."

6:45 p.m. - Comments from Jeff Burton, driver of the No. 31 Caterpillar Chevrolet, who finished third in Sunday's Shelby 427:

(On his team's pit strategy) "I think it was no tires, actually (on the last pit stop). I don't know why we're always better on old tires. We took off there and led the race for a long time and came in and put on four and then went back to sixth or seventh and that's been a struggle. I'm real proud of all our guys. Hell of a rebound today to come back from where we ran last week and everybody just kept their head up and kept digging. I'm real proud of them for that. It's real easy to quit and give up when things are going badly. Our guys never do that."

6:20 p.m. - This marks the fifth consecutive season in which Kyle Busch has won a race in all three of NASCAR's national series. He won the Camping World Truck Series and Nationwide Series races on Feb. 21 at Auto Club Speedway in Fontana, Calif.

5:35 p.m. - Kyle Busch on winning the Shelby 427 at his hometown track: "This is great. I didn't know exactly what it would mean but coming to the checkered flag, there were knots in my stomach. This is as big as the Daytona 500 - I said it wasn't going to be, but it is."

5:25 p.m. - Las Vegas native Kyle Busch wins the Shelby 427 NASCAR Sprint Cup Series race after starting from the rear of the field. Clint Bowyer finished second and Jeff Burton was third. Stay tuned for more information and comments from the top drivers.

"I hate it. I sure would have liked to have kept racing today. We had a good racecar and we were getting better. And we're learning each week. We'll have to get ‘em next week."

(Did you have a shot to win?) "Well, not yet; maybe with some adjustments and maybe with some track changes. We were within striking distance. We weren't quite good enough yet but we were within striking distance."

2:56 p.m. – Comments from David Ragan, driver of the No. 6 UPS Ford, who dropped out with an engine failure on lap 73:

“On the restart, it just started skipping and popping and we switched ignition boxes because I felt like it might just be something small but it kept getting worse and worse and just wouldn’t go down the straightaway. I’m pretty proud of our UPS car so far today. It wasn’t great but we picked it up some and seemed to be in decent shape to make some more adjustments, but it looks like something just let go in the engine.”

(Is it the same thing as Matt Kenseth?) “I would suspect so. All of the engines come from one source and they al do a great job – knock on wood. In four years at Roush Fenway, this is the first time I’ve had an engine failure. Things like this happen when you’re always trying to get the most out of things and I’m just disappointed it had to happen this early in the race. I wish we could have at least got to race some more.”

2:30 p.m. - Comments from Matt Kenseth, who dropped out with an engine failure on lap 7:

"I think it had some kind of valvetrain issue. That's basically what it sounded like, so I don't know. Something busted in there. It's disappointing we didn't get to race today, but those guys do a great job on engines. Doug Yates and those guys, without their horsepower, we couldn't win races like last week so I can't really complain about those guys."

(Were you thinking about the history of winning three in a row?) "No. Winning the third race, seriously, was the farthest thing from my mind. We approach it one race at a time and I'm very, very thankful for the first two weeks of the season that we had and for the opportunity to drive this car. You're gonna break stuff once in a while. I think it's the first engine we broke in two years. The guys at Roush Yates engines do a great job. It's bound to happen sooner or late, it just didn't happen at a good time. It happened at the beginning of the race, so it's just one of those thing that happen."

2:18 p.m. - Shelby 427 running order after 50 laps: Jimmie Johnson, Carl Edwards; Kurt Busch; Kevin Harvick; David Stremme; Mark Martin; Greg Biffle; Tony Stewart; Sam Hornish Jr.; Jef

1:57 p.m. - The race already has had two caution periods in the first 10 laps. The Sprint Cup Series record for most cautions here is 11, set last year. Matt Kenseth, who blew an engine on lap 7, is the first todrop out of the race.

1 p.m. - This year's Sprint Cup race at LVMS, the Shelby 427, will be 18 laps - 27 miles - longer than the previous Cup races here due to Shelby Automobile's sponsorship of the event. Shelby Automobiles, founded by automotive legend Carroll Shelby, is using the event to market a Las Vegas Motor Speedway Limited Edition Shelby 427 package for the Ford Shelby GT500 Mustang. Shelby's manufacturing facility is the anchor tenant in the business park adjacent to the speedway.

11:30 a.m. – Some quick facts about the NASCAR Sprint Cup Series at LVMS: Five drivers have participated in all 11 Cup races at LVMS: Jeff Burton, Jeff Gordon, Dale Jarrett, Bobby Labonte and Mark Martin ... Only four of the 11 races have been won from a top-10 starting position ... The race has never been won from the pole ... The deepest in the field that a race winner has started was 25th, by Matt Kenseth in 2004 ... The first Cup race held in Las Vegas was in 1955 at Las Vegas Park Speedway, which sat on the site of whatis now the Las Vegas Hilton.

11 a.m. – Carl Edwards, who survived Saturday’s caution-filled Sam’s Town 300 and finished second to Roush Fenway Racing teammate Greg Biffle, said he doesn’t expect today Shelby 427 to have as many incidents as the Nationwide Series race.

“I don’t think so (because) I think the cars are so different,” Edwards said. “They’ve got too much downforce, the Nationwide cars do, for the power that they have so they’re like slot cars; you’re riding around as freed up as you can be and if any one little thing happens, it’s really hard to correct.

“The Cup cars aren’t quite like that. They’ve got a little less downforce and a lot more power so you end up being able to drive them more and save them a little bit if they get loose. I hope that’s the case -- that they’re easier to handle and it won’t be a big disaster.”

Edwards is the defending champion of the Las Vegas Sprint Cup race. He also finished sixth here in 2007.

9: 50 a.m. – Jimmie Johnson has three Cup victories at LVMS but Matt Kenseth actually has a better overall track record here. In nine Cup races, Kenseth has a pair of victories, five top-10 finishes and an average finish of 9.0. Johnson, in seven races, has three wins, four top-10s and an average finish of 9.3. Kenseth has been running at the finish of all nine races and has been on the lead lap in eight of those races. 

“There are a lot of things I like about Vegas,” Kenseth said in explaining his success here. “Obviously, the track is different than it was a few years back when we had all the success here, but it’s fun, it’s high-banked, it’s real fast. It’s actually got some pretty big bumps in it, which makes it challenging. It’s just a fun place to come out to this time of year and it’s a fun, competitive track.”


9:20 a.m. – Good morning from Las Vegas Motor Speedway, where a sellout crowd is expected for the Shelby 427 – the 12th NASCAR Sprint Cup Series race to be held at the 1.5-mile speedway. Forecasters are calling for a high of 75 degrees today with mostly sunny skies and – more important – zero chance of rain. The race is scheduled to take the green flag at 1:30 p.m. (PST). Check back here often throughout the day, as we’ll be updating this blog with news, stats and driver interviews.
