      2000rpm would be too slow for my engine configuration. I want to cruise around 2500rpm. The problem is that every engine is different and the cam has a big impact on optimum rpm range. Generally speaking, a 3.73:1 or lower rear gear would be my starting point for an over drive trans. A 3.50:1 or taller works with a 1:1 non-OD trans.
