Yeah, one of my best sources is one of the cylinder head development guys for Hendrick.
Us drag racers kind of get the hind tit when it comes to engine development and the stuff it takes to make an engine live . . And the NASCAR guys aren't to good about spreading any know how around . . Most of the stuff we're doing now, NASCAR was doing 10 years ago . .
Of course we can't spend several million developing a new head or lower end, either!
