I guess people forget that Jake King was a ford mechanic, before being paid to built hemi's...
Or that Ronnie Sox started out racing Chevys before being paid to race Mopars...
Or that King Richard was paid to race a Ford in 1969...
Or that Grumpy Jenkins raced Mopars before going to Chevrolet...
When racing is what you do for a living...brand loyalty goes out the window, if the money stops coming in.
If you have a successful racing operation, making large amounts of money, racing a Mopar, then all of a sudden Mopar pulls the plug on funding, but GM or ford are willing to support you, are you going to continue to race out of pocket due to brand loyalty, close up your operation, and take a job in a factory somewhere, or go where the money is??

Brand loyalty is fine for the average car guy, but not when it's your business/lively hood.
