Fords continue to dominate testing results … Rookie Erik Darnell (No. 99 Roush Racing Ford) topped the morning's single-truck speed charts with a lap of 178.951 mph as temperatures plummeted more than 20 degrees from Friday and drivers battled stiff winds. Jon Wood (No. 20 Wood Brothers-JTG Ford) was second-fastest at 178.696 while Darnell's teammate, David Ragan (No. 6 Roush Racing Ford) stood third at 178.377.  That caught the attention of three-time NASCAR Craftsman Truck Series champion Jack Sprague (No. 60 Con-Way Toyota), who stood 12th in the morning session.

"Those Fords are stupid-fast and I think they're legitimately fast (by the Rule Book)," said Sprague.

Sprague was asked about how the level of competition in the series has changed since he won his third title in 2001. "From where the bar was then, now you can't even see the bar," he said.

Last year's pole winner Kerry Earnhardt (No. 13 ThorSport Chevrolet) recorded the afternoon's fastest single-truck lap at 177.445.

Crocker expects measured results in 2006 … Erin Crocker (No. 98 Cheerios/Betty Crocker Dodge) told media members that last season, during which she split time in NASCAR Craftsman Trucks, NASCAR Busch and ARCA RE/MAX series, was enlightening in two respects.

"There were a lot of things I learned to do and a lot of things I learned not to do," said Crocker.

Considering she's new to her Evernham Motorsports crew and that the Daytona truck wasn't completed until just before the team left for Daytona, Crocker called early results encouraging. "We're on the same page … but it's going to take some time. So it could be a slow start to the year," she said, adding, "I want to win. I want to prove I'm competitive and that I can do it."

Hamilton lauds engine rule in place for Daytona 250 … The addition of a .990-inch spacer between intake manifold and carburetor, which reduces the flow of air but doesn't affect fuel flow, has resulted in slower practice speeds. And, according to the elder Hamilton, it still gives the driver plenty of throttle response. "It's the best rule they (NASCAR) have made [for the Daytona 250]," he said. Teams for the first time also are required to mount a right side window. NASCAR will evaluate test results before issuing specific procedures for the Daytona 250.

A third and final day of testing begins at 9 a.m. Sunday and concludes at 5 p.m.
