No snubber, just (new) stock, rear shocks.

You need LONGER shocks when using the SS springs. Read this: http://www.forabodiesonly.com/mopar/showthread.php?t=3558

You need to work on your suspension and getting traction.

When you tune your jets etc, tune for fastest MPH not ET. ET is traction based and same for 60ft
