Sammy,
Actually Swain is about 10 miles from my house. Let me call Dan out there and see if I can get some solid quantitative, apples to apples data to specifically answer your questions. I know that Joe Sherman was mentioned in an earlier post regarding his win at the Engine Masters competition...
Sammy,
Give these links a try. I will see if I have some actual dyno results to quantify the claims.
