Ok... Just running the numbers again.

The 302 (5.0) NA 3017/350 = 8.62 natural B car until it gets 5 hp.
3017/355 = 8.49 making it a natural A car. I don't see this combo competing with '10 428 combo in A.

The 363 NA combo. 3100/330 = 9.39 making it a natural C car. Probably the best combo they've got here. It would need 15 hp to be a natural B car.

The 427 NA combo. 3150/425 = 7.41 making it a natural BB car. In my personal opinion this combo would not run with the '10 428 combo.

The 5.0 SC combo. Well I'm not a SC kind of guy so to speak but coming out of the box at 500 hp is pretty steep in my opinion as well. I would really like to know what happened between Ford and NHRA here. I guess Ford had to throw them a bone?

The '10 352 combo 3130/285 = 10.98 making it a natural F car until it gets hit 13hp to 298 hp then its a natural E car.

The '10 428 combo 3305/375 = 8.81 making it a natural B unit it gets14hp to 389 then it will be a natural A car.

So you've the '13 5.0 NA version competing in B against the '10 428. I don't understand.
