Understanding Oval Track Cranks & Rods: There’s more to it than you think

Racing’s racing, right? The first one is the winner and second place is just the first loser. While that may be true as far as it goes, getting across the finish line first takes different techniques depending on the type of racing it is. Racing engines are not immune to specialization.
