I would also have to wonder if some from Roush-Yates engines might have decided to seek employment elsewhere??? Penske has always had a first rate engine shop no matter what the form of racing!!! His guys got more out of the Dodge's then Petty or anyone else ever could!!!!

But yeah, I would imagine there is at least some back door help coming from Ford and Roush....

Robert Yates was always famous for hangin' back a bit in off season testing, I doubt Doug is a whole lot different.... Let em wish for awhile, then blow them away!!!!!!!
