Craig,
You won't get a Ford bashing comment from me, I'm probably the least brand-loyal guy in here.
They lost some engines a couple weeks ago due to fuel related piston failure, one to a crank failure (2002 design crank), some to
oil/rpm bearing failure.
They're making more power this year, but say that is not the reason except in the case of the failed crank.
Last fall it was Hendricks Chevys blowing up, so it goes around.
