This is Blaney's rookie season in trucks, driving the No. 29 Ford for Brad Keselowski Racing. He has two career wins in the series -- Iowa in September 2012 and Pocono last month.
"Any time you win in any series, your confidence level as a driver goes way up," Blaney said. "You hope to make something of that momentum going into the next week and just still keep building off of that and having good runs after that."
After finishing third in the most recent race earlier this month at Chicagoland, Blaney moved up two positions in the point standings to fifth. He is 82 points behind leader Matt Crafton. This will be the first time Blaney competes in a truck event at Las Vegas.
"We definitely got into a little bit of trouble earlier in the year, whether it's mechanical issues or just being in the wrong place at the wrong time and ending up with a wrecked truck," Blaney said. "But I think my Brad Keselowski Racing team has really improved here over the past few months with winning Pocono and having a good shot to win Bristol and running up front in Chicago.
"We've had a lot of good runs the past few months, and it's unfortunate we got ourselves so far behind in the first half of the season, but that's what racing is all about. The 88 team (Crafton) has done an awesome job of really being consistent and really being able to build up that huge point lead."
Crafton comes to Las Vegas with a 41-point lead over defending series champion James Buescher, who has won two of the last five races. Ty Dillon is third in points (-59), while Jeb Burton is fourth (-70).
Twenty-nine teams are on the preliminary entry list for the Smith's 350.
