Yes it does change things. Not sure wagons are eligible to run SS GT.

Jeremy I found a picture of Greg Luneack nova wagon with gt/ha and ss/ka on the window

66 Chevy II Wagon was available as a 2-door, which is a requirement for GT. Check the weight and go from there.

Yes it does list station wagons in the rule book

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"

3062/327 = 9.36 lbs per hp.

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

9.36 x 295 = 2761 (pick one)
9.36 x 307 = 2874

"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."

2761/295 = 9.36
2874/307 = 9.36

GT/GA 9.00=9.49 lbs per NHRA factored HP

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

+250 =3011 = 10.2 NHRA factor GT/IA 10.0-10.49
-250 =2511 = 8.5 NHRA factor GT/FA 8.5-8.99


EDIT


Indexes
GT/GA 10.40
GT/IA 10.65
GT/FA 10.25

Marks right, regardless of what some website may claim, there were no 2 door Chevy 11 station wagons made, at least by GM. you may have seen a couple of 2 door wagons around Seattle, like Al Chinns Nova, but that was fabricated, not original. That said, Chevy did make some 2 door Chevelle wagons in 1964 and 65. Pat Brooks runs a 64 Chevelle 2 door wagon in Stock in Div. 6, and also has another street 64 2 door wagon. But other than the 64-5 Chevelle, there were no Chevrolet 2 door wagons after 1960, until the Vega came out in 1971.
