Damn it can't be that hard to get a fbody to get it done off the line... I have a friend with an 02 ws6 that cut 1.65's with COMPLETELY STOCK suspension and 295/35/18 bfg gforce drag radials with a cam/bolt ons/stall.

Get a good set of tires, take off that front sway bar, and get a 3600-3800 stall and see if your desired 60ft has been reached. No need to go apeshit on suspension mods if you don't need to do so.
