And when over-balancing, by how much is the balance factor adjusted, e.g. 1%?, 2%? Is this combination a candidate for over-balancing? - 650 (est) HP street/strip application w/ emphasis on track performance - expected shift RPM of 6500+ and peak RPM est. of 7200 on big end - 3.75" stroke 440 w/ steel rods - standard bob weight calc = 2496 grams - highway cruise RPM (driving to & from track) ~3500
