Davis' announcement came days after Jim Aust , who heads up Toyota's racing effort, walked away from his post.
Brian Wolfe , 47, will replace Davis at Ford.
"For me, a kid from Michigan whose father idolized Henry Ford , there was never any doubt where I was going to work," Wolfe said.
"To have this opportunity now to take the racing program forward is a dream come true."
Ford won three driver and four manufacturer's championships in the Sprint Cup Series under Davis, and he was behind eight Funny Car championships in the NHRA.
He also helped create Roush-Yates Engines, a company that provides engines for the majority of Ford teams in the Sprint Cup, Nationwide and Craftsman Truck series.
Wolfe was responsible for all powertrain computer control software applications. He's been with Ford for 26 years.
MOSS BUYS TEAM: New Eng-land Patriots receiver Randy Moss now owns a Craftsman Truck Series team.
Moss bought Morgan-Dollar Motorsports recently.
The new team, with No. 81, will be called Randy Moss Motorsports. Moss hopes to debut his team at Kentucky Speedway on July 19.
A formal announcement is expected today at Daytona Inter-national Speedway. Moss expects to introduce his new driver then, too.
"The companies I already work with now have a chance to get some exposure to another group of dedicated sports fans," Moss said.
"And we'll have a chance to do some pretty cool things between the football side and the racing side. That's part of the equation that most of the other teams don't have, so we already have a competitive advantage over them. Once we get everything in place, we look forward to competing on the racetrack."
JUST TESTING: NASCAR may lift restrictions on testing next year. Teams currently are limited to NASCAR-sanctioned tests at Sprint Cup tracks. They are allowed to test at non-Sprint Cup raceways.
Car owners, however, don't seem to like the idea. Richard Childress said it would increase operating costs by more than $1 million a team.
Series competition director John Darby told the teams there were several options under consideration for the future, including the elimination of all testing.
PIT STOPS : Aric Almirola will drive the No. 8 Chevrolet at Dale Earnhardt Inc. on a full-time basis in 2009. The team decided Almirola's development was being delayed by Mark Martin's part-time schedule... By leading 132 laps at New Hampshire last week Tony Stewart became the 13th driver in NASCAR history to lead more than 10,000 laps in his career.
