I just took our heavy Chevy Monte Carlo to the track for the first time and averaged in the 15's (Boo Hiss) and that's even with using nos.

Ok how can I tune the car for optimum acceleration? What carb is best, Holley or Edelbrock (both are 600's) Do I pull the vacuum
advance hose? How rich a mixture for gas? What gear do I apply the nos? Should I use a cool can? What static timing is best? 8 or 12 BTDC? What tire pressures? (Street tires 205/70r/15, fronts 235/70r/15s back) How much air in air shocks? Do I loosen the front stabilizer bar? Do I use the lightest centrifugal springs in distributor?
Or is 15s all I can get out of a street Monte Carlo?
