Also head that the dart head do "not" make any more power than the GM heads, they are thicker and probably will not crack after porting. My head only cracked on the external part of the head above head bolts. Told because the head surface had to much angle milled.

Being one of the longest CS drivers, what ever after market company gets approved, the head for GM should remain 23 degrees. Would save some money in combinations, Intake and maybe pistons. Back when the class was created it was for what was available at the time(cast iron) in the 70's, modified eliminator days. For GM it was the 23 degree heads, I believe the turbo heads. MY opinion only.

Dart offers a 23 degree Iron Eagle Platinum 230cc Intake runner cast iron head with a 49cc chamber flowing 308 CFM's out of the box. World Products offers the Motown 23 degree cast iron head with a 220cc Intake runner. Let's not forget that there are still some of the RHS/Pro Topline, 23 degree cast iron heads out there with as cast, 245cc intake runners too.

Bruce told me directly the two part numbers I dont have the numbers here at home, but I looked them up right away and one was the existing Dart 180 cc currently legal in the traditional classes, the other IS the 230cc/49cc Dart previously mentioned, Those are the only two on the list as of my conversation with Bruce.

Regarding Mr Bogner's comment about cracking, I agree, if your heads are cracking then maybe you just went to far? I have two sets of N heads that have cracked ironically across the exhaust face from the head bolt bosses, wrote it off as just bad castings. Manned up and built another set.

Were there any 'non-Factory Stock' combinations running in the 6.00 to 6.49, 6.50 to 6.99 or 7.00 to 7.49 classes in Stock? If so, where do they fit now?

Do they have to add weight to fit the 7.50-7.99 class or could they run with the FS cars? Or are they ineligible to race now?

(Reference pg 29 of the 2014-2015 amendment.)

It's unchanged. They just moved it to General Regulations.

According to Nitro Joe's Stats for 2014 only one 1969 Camaro ran in BB/SA. It was a 427 430/445 with a natural BB/SA classification. At another race the same car added weight and ran CC/SA. For 2015 any older car that falls 7.49 or higher in Stock must add weight and move to the new 7.50 AA class.
