I really think people have gotten so used to the new OD transmission where the engine turns at 2200 at 75 that they think they are doing harm to the motor when it revs . Cars and trucks put 100s of millions of miles on the highways doing 75-80 @ 3000 + RPS . My Chevelle turns 2900 and change at 60 mph . I've driven it for hours at 70-75 going to Carslisle ,Syracuse nationals and Goodguys shows. Little noisy yes did it damage the motor? Hardly
