Curtis, use your best asset, old age and treachery. I used it for years, it works well.
And, a long, long time ago when talking to Bob Tillius, he gave me some very sound advice. I had asked him as a racer, what should my priorities be? His response was immediate, a reliable tow truck, so you can get back to your job on Monday. And, a chassis tune is much more important than horsepower. It is not about the most HP, just competitive, reliable HP. He had a few Championships with British Leyland.
In road racing, it is handling, weight and aero that are more important than horsepower. I have used his good advice very succesfully for more than 30 years. I look for more horsepower, only after the chassis and the driver have been optimized. Many people are surprised when I tell them I typically run 2 seasons before refreshing a motor. And even longer with GT1 V-8's. It is easier on the motor when the chassis is dialed in. You can reduce lap time more from the development and money spent on the chassis than with 20 or 50 more HP. And you spend less money repairing a highly strung motor. I don't like having a loose pin on a grenade in front of me... Never cared for a 28 minute motor in a 30 minute race either!
