Though driver/owner Michael Waltrip said Joe Gibb's Racing's switch from Chevrolet to Toyota beginning next season has already benefited his first year Nextel Cup team, President J.D Gibbs said his organization has yet to begin serious work on its new engines.  We've been real careful Gibb said.The car fanatic that we are, we obviously had conversations about what it looks like.  But once this year is over we'll sit down and see what it looks like. As of rite now we haven't done a whole lot of stuff.  We want to be careful and we want to finish out strong for GM. Then when the time comes, we'll look at some other projects.  Our biggest thing will be starting  the year with the engine program that is the hardest thing we do.  We love our cars.   If you are into racing and reconstructing of your car, go online for the best deals yet.  The net is a good place to look for discounts.  Click here for more information.
