NASCAR Craftsman Truck driver Rick Crawford and the folks at Ford Racing planned to use all of Thursday to learn the ins and outs of the new 2004 Ford F-150. Instead, they lost an engine only 2 hours into the test and had to pack up and head home. ¿We didn¿t get nearly as much on-track time as we¿d hoped for on our maiden voyage, but I think we still learned a lot,¿ Crawford said. ¿This truck has a lot of promise and potential. We were creeping up on it; every run was faster and faster. This truck has surely not reached its peak.¿ Still, in the 25 or so laps Crawford was able to run, he managed a top speed of around 170 mph. ¿Today was just about getting ready for 2004, trying to get a leg up,¿ said Robert Brooks, NASCAR truck program manager for Ford Racing. ¿We¿ll give all of the information we gathered today and give it to the whole Ford family for next year. It wasn¿t as much as we¿d hoped for, but it¿s still a great start.¿ Crawford and several other Ford drivers were in Atlanta just last month to test different tape configurations on the front air dam, measuring how much it changed the trucks¿ cooling system and downforce. ¿Between that last test and this test, I have a real comfort zone here in Atlanta,¿ Crawford said. ¿This is a great, fast track. I wish I would have had the afternoon to play around with the new truck, because we were pretty conservative in the morning, but we feel good about how things went.¿
