Actually the 2.3 would stack up pretty good leaving the line and for the first 100 or 200 feet but after that its all over. If you have a Carpenter bike you might win. The beauty of the Chopper is that its always like a Carpenter bike with twice the torque but its not hopped up. Its just a 350 Chevy ZZ4 crate motor, like an older corvette. Its just proof that nothing can compare with cubic inches, thats why our 140 cu inch Rockets are so impressive, they are the biggest engines in any mass produced bike. The problem is as the engine gets bigger so does everything else. A small engine can be made to put out incredible horsepower but at the expense of engine life and reliability and a narrow hp/torque range. The Rocket is a compromise, large reliable motor with good power and torque, yet still light enough to handle decently.
