You can't win a race with 250hp, but you can win a race with 300tq. I'd rather be under than over on torque. I don't see how the rule change proposed would favor an LT1 the least little bit. The car came with the underdrive and I hate to take it off because I'm sure it helps the alternator and PS pump to live longer. On the other hand, it's free and easy to do. Car needed a belt anyway.
