Default Re: gt class question

3062- 250= 2812÷ 295= 9.53 pw factor LIGHTEST
3062+250= 3312÷ 295= 11.23 pw factor heaviest

GT/HA is 9.50 to 9.99 pw factor. This would be the lightest class he could run. CAN NOT GO TO BOTTOM OF CLASS THOUGH.

GT/KA is 11.00 to 11.49 pw factor this would be the heaviest class he could run.

GT/HA min 2980 index 10.50
GT/IA MIN 3120 INDEX 10.65
GT/JA min 3265 index 10.80
GT/KA min 3415 index 10.90

GT/JA still seems like best choice for ya. Add 25lbs from your SS/IA MIN WT & GET a tenth in index.

Cool car by the way. Don't see very many 327 Wagons running SS/IA.
