BROOKLYN, Mich. (AP) _ Maybe it was the extra testing. Maybe it was the vacation in Cancun. Whatever the case, Buckshot Jones was faster Friday than he has ever been in a NASCAR Busch Series car.

Jones, with a one-lap speed of 184.786 mph, won the pole for Saturday's running of the NAPAonline.com 250 at Michigan Speedway. It was the third Busch pole of his career and his first in 23 attempts this season.

Matt Kenseth will start beside Jones in the front row. He had a run of 184.030 mph. Jones and Kenseth both drive Chevrolet Monte Carlos.

Jones took one of the two cars used in a test at Michigan in July to the wind tunnel early last week. The Cheez-It team was trying to learn more about the Monte Carlo and fine tune the car for Michigan this weekend.

This is only the second time Jones has competed with a Monte Carlo on a 2-mile track in the Busch Series. The team made the switch from Pontiac to Chevrolet in April at California.

``I was real happy with our testing here in July,'' Jones said. ``Between the track testing and what we learned in the wind tunnel, I think we should be pretty good.''

Saturday's race will mark the first time the Busch Series has run 125 laps at Michigan. Busch races in the past had only been 100 laps at this speedway.

``I think the additional 50 miles will really change how the race is run,'' Jones said.``Typically, fuel mileage plays a factor at Michigan. But with 50 extra miles, I don't think you will see teams gambling too much on gas.''

During the week off after the testing, Jones and his family vacationed for several days in Mexico.

``I'm looking forward to getting back,'' said Jones, whose best finish in a Busch race at Michigan was fifth in 1997.
