RE: Best way to improve off the line performance
I will elaborate for you John.
The main problem with D17s is they're improperly stroked for the engines design. The stroke is too long for it, which breeds numerous undesirable conditions. It won't be able to carry torque well beyond midrange rpms. Stress on all bottom end components will increase (as compared with a shorter stroke), as a result of accelerated piston speeds and greater levels of vibration caused by the long stroke. The wrist pin placement (used to offset the motors horrible rod to stroke ratio) is also in an undesirable location, so I've read. There's probably more, but I'm not a mechanical engineer.

You want power off of the line? Its so simple, you wont believe it. You need 2 things.........Torque, and sticky tires.

that's like asking "where do I buy decibels for my sound system?"
