The fact is that there are a select few that have been pushing the spec motor class for a VERY long time. Any post they can get their foot in the door, off they go on their rant about how much better a spec motor class would be. Well here are a couple news flashes for you: 1) All S and SS classes are already spec motor classes. And year after year, the costs go up. WHY you ask? Because people constantly push the envelope. If someone is willing to spend 10K on a set of heads, what does that do to the rest of the field? I'll tell you what it does. It takes them out of contention or it forces them to spend the money to keep up. 2) If you think adding a spec head will solve anything, the only one you are fooling is yourself. The dirt track guys have been working around the spec head issues for years. They know how to port around the runner markings. They also buy pallet loads of heads and flow all of them to pick out the best ones. WHY? Because the spec head rule is just another rule builders and racers must work around. And there is ALWAYS somebody willing to spend money to be faster than the next guy. And that forces the next guy to spend money. And then the next guy.... And in the end, everyone is spending more money because of the spec head rule. 3) I don't see how you draw a link between dwindling spectators and the lack of heads up runs. Spectators just don't care about drag racing anymore. There isn't enough drama in it. OH, heck yeah, they will sit at home and scream at the TV watching their favorite episode of street morons. Or sit through the dirt of a roundy round short track race to see who takes out who on turn 4. But they really have no interest in watching two cars race down a safe race track. 4) As for new blood in the sport, that's pretty simple. The cost is a big one. Unless you have a great sponsor OR you own a profitable business, how do you think anyone can enter this sport? And time off to race is probably the next biggest obstacle. Who gets 3-4 weeks vacation a year to spend on racing? How you think a 20 to 35 year old person, with a home, a family, most likely some student loans and car payments.....can spend the money it takes to finance a decent car and go racing for 3-4 weeks a year? Lastly, did you actually intend to use a comma rather the an apostrophe in your signature? That is to say it should be "don't" instead of "don,t" |

Re: SS Modified
In SS Modified where they say 2 4 bbl carbs or 3 2bbl carbs maximum, would they allow a single Holley Dominator carb or a single Holley 4150? SS/AM - SS/GM

Re: SS Modified
I know several guys who simply change the designation on their window from BS to CM without changing anything. Weight break is the same only difference is .15 in index.
I can only assume it is legal to run CM with 1 carb. |
Re: SS Modified
To crossover from SS/AS - SS/CS possibly or Comp Super Modified classes. Could probably run close to the index, sure it would be down on power from a dual carb set up.
Don't know if anyone has do that or is legal with with one carb. |
Re: SS Modified
You can definitely run under the index w/ a single carb. I used to run SS/PCA in IHRA, which is a single dominator that would fit in SS/BM at NHRA events and could run a couple tenths under but that's it. There's usually around 30 more hp w/ two carbs but I didn't have $2000 for another intake plus the cost of a set of carbs.

Re: SS Modified
I heard from guys during PRI show the part number rule was thrown out and any head is legal in modified now? I'm sure there's limits like sohc or dohc maybe? Anyone know?
Sorry if I'm missing something. I've been out for a while. Just getting back in with new car. Stacy |
Re: SS Modified
The rule was changed to state aftermarket heads allowed, but, they still would have to be NHRA accepted aftermarket head and listed as an accepted head with the part number of the accepted head.
Currently there are none listed. You will have to go through the acceptance process to have a head accepted. |
Re: SS Modified
Well if any aftermarket is approved but there's acceptance required then It's just a question of rulebook semantics. Nothing different.
Also do they allow any bore spacing now? I heard sbcs but not bbcs? Stacy |

Re: SS Modified
From 2015 Rule Book,"Two NHRA-accepted American-production 4-barrel or three American-production 2-barrel carburetors maximum. Inline 4-barrel carburetor prohibited. Fuel injection prohibited."
It doesn't give a minimum. One 4-barrel is legal. |

Re: SS Modified
That's why you should use your phone for your division.
I have tried lots of things, and when questionable I call, or take with me to a race, then ask If I can use it. If your really worried call the National office. JUST call! If you did call them and they said no, then why would you think that it will change by chewing on it in a forum? If the answer was "no" don't gamble, get over it. Go find some carburetors. Have fun, get your stuff together and come play! These classes while challenging are very rewarding. |
