Weight transfer basically means shifting the weight balance of the car upon launch to the rear wheels. When the car's setting on the ground on all four wheels, you may have something like a 55/45 split of that weight front to rear. If you launch and pull the front wheels up, that split has now gone to 0/100. Planting that weight on the rear wheels means added normal force in the contact patch which equates to a higher frictional force in the contact patch => more bite to prevent spinning of the wheels. Well matched suspension components enhance and control this weight transfer. A good combination of springs, struts, control arms, pinion angle, etc. will maximize not only the weight transfer, but the control of the car when it happens.
With your combination, I don't think there's much chance of you overpowering those 10" slicks. Take your launch RPM up to about 5000 and dump the clutch. But be forewarned, if you're still on stock axles you're just asking for trouble. They may go 200 passes or 20 passes. Do yourself a favor and invest in some Moser axles.
