I'm not sure if 400.00 for this would give this a worth while increase in torque at the rear wheels at take off. Any opinions?

A lighter flywheel will actually soften the initial hit on the tires at launch but the engine will accellerate quicker. We usually use a heavyweight flywheel on a car that is heavy to hit the tires harder to help get it out of the hole better. If your car already has traction problems or is light or has a weak drivetrain (i.e. 700/t5 and 10/9 bolt) then a heavier flywheel will do you no good.

 

The GM lightweight flywheel (from 30 pounds to about 16) is perhaps an option. The cost for a 305 is considerably less than the one posted in your link. Depending on what motor you have, you may already have the lightweight version.

If you're trying to drag race the car, a lighweight flywheel won't do you much good. Just like Formula355TPI said, but also between shifts the inertia of the heavier flywheel keeps the motor from dropping too far below the power band.
