It will be pretty disappointing to change the rules when so many others have made the numbers only to try and give a particular motor the "perfect number". What about my little LS1 that only makes 292 tq? It requires such a small plate to knock down the hp that it kills the torque-it's just part of it. So it's kind of tough to see complaints when a motor is over on both tq and hp. If the rules are changed then they should allow tuning so I can get a perfect number with my car.
I think Glenn is correct on the lash and exhaust can have an impact. I believe you would want a bigger exhaust to cut down torque and the byproduct is likely going to be more hp. Yeah I don't see the need for the pulley when you are over now.
