D.L., there was a rule at one time about using "the heaviest V8 gasoline engine", or something to that effect. I would guess that means using the shipping weight of a particular vehicle, using the shipping weight of the heaviest gasoline engine available in that particular body style (I can;t find my rulebook to verify).

(edit) From the 2008 NHRA Rulebook, for SS/GT (car):

"Shipping weight of vehicle can may be adjusted a maximum of 250 pounds to fit car in class, provided shipping weight does not drop below 2,500 pounds. Car can move up or down in classes. If weight is added, must be properly attached; see General Regulations 4:2. Shipping weight will be determined by using the power to weight factor of the vehicle with the heaviest gasoline engine and appropriate transmission, and multiplying the factor times the horsepower or performance rating. The proper class weight will then be determined by dividing this figure by the horsepower or performance rating of the engine used. Class is determined without driver weight. Once Classification weight is calculated, 170 pounds will be added for driver to arrive at minimum weight".

For GT truck, it states the following in the '08 Rulebook:
"Shipping weight of vehicle can may be adjusted a maximum of 250 pounds to fit car in class, provided shipping weight does not drop below 2,500 pounds. Car can move up or down in classes. If weight is added, must be properly attached; see General Regulations 4:2. Shipping weight will be determined using the power to weight factor of the 1990-2007 vehicle and multiplying
the factor times the horsepower or performance rating of the engine used. Class is determined without driver weight. Once Classification weight is calculated, 170 pounds will be added for driver to arrive at minimum weight".
