gt class question

[FireSale]

This math has been corrected.
66 Nova wagon is natural GT/KA and sits at the top of the weight brake.

Sorry for the math screw up.......

Station wagon shipping weight is 3062. The heaviest auto gas V8 is the 327/275. It has a SS rating of 307 and a GT rating of 295 with OEM heads. I don't know which to use. Classification weight is figured without factoring in driver weight.

Quotes are from the 2019 GT Weight section. Math is mine and not under warranty....

"Shipping weight will be determined by using the power to weight factor of the vehicle with the heaviest gasoline engine and appropriate transmission"

3062/275 = 11.13 lbs per hp. 3062/275 = 11.13 X 295 = 3284

"..and multiplying the factor times the horsepower or performance rating"

11.13 x 295 = 3284 (pick one)
11.13 x 307 = 3381

"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."

3284/295 = 11.13
3381/307 = 11.00

GT/KA 11.00-11.49

"Shipping weight of vehicle may be adjusted a maximum of 250
pounds to fit car in class."

HEAVY MAX
+250 - 3534 = 11.98 NHRA factor
GT/LA 11.50-11.99

LIGHT MAX
-250 - 3034 = 10.28 NHRA factor
GT/IA 10.00-10.49
