No those pages refer too traditional SS. Not GT. Gt weight rules are on page 124 and are like you stated prior.
For example:
1968 Plymouth Barracuda for GT
Shipping weight would be 3254 Got to use heaviest wt with V8 engine and same style (Fast Back) which is the 383 version.
Shipping weight can be adjusted 250 lbs + or -
So if you use a engine factored at 300 hp lightest class would be GT/E(10.0-10.49). 3254-250/300= 10.01 power to weight factor. Minum weight for GT/E would be 3170. 3004lbs +170 for driver. Rounded down for scale weight to 3170.
Heaviest class @ 300 hp factor would be 3254 + 250/300 = 11.68 p/w factor. which would be GT/H (11.50-11.99) Minum would be 300 hp x 11.5 +170= 3620.
So in the above example the cuda could run GT/E @ 3170, GT/F @ 3320, GT/G @ 3470, & Gt/G @ 3620.
Where some cars run into problems is when they fall into the middle of a class. Then they can not go to the the min.
Also some older car styles that came with Big blocks have very heavy GT shipping weights. For example 1st gen camaros and 2nd gen & 3rd gen corvettes.
