At what point in a car show does the break from stock to modified class happen? I have a 1978 Pace Car (Low miles) that I have installed the Edelbrock Air Gap dual quad carburator on. Not for go, I just like the apperance of them. This is the only change I have made. The rest of the car is as from the factory. Should I now expect to be placed in the stock or modified class???
Thanks
Jackie

Unlike being judged by NCRS or Bloomington Gold, most garden variety show and shines and club sponsored events make up their own rules. You will have to familiarize yourself with the rules of whichever show you enter to determine the class you should be in. I would guess that most local shows would consider your car basically stock if the only modification is the intake and carb and all else appears stock.

i've done all kinds of shows over the yrs. I used to have a 65 GTO that was all stock except for headers. Some shows put me in stock. Some in modified? Depends on the show. organizers. And the other car owners. I had many an owner complain about headers not being stock to judges. Was also fun when someone complained about the 3 carbs on it not being stock. LOL. Agh, the young crowd.
From: Arlington Va Current ride 04 vert, previous vettes: 69 vert, 77 resto mod
we entered our 77 vette in a modified class and the guy taking the $$ (the judge) said thats our car was not modified because of what he saw on the outside and got into a pissing contest with my son who said BS....its got non original high performance motor, overdrive trans, dual exhaust h pipe,rack and pinion steering,etc,etc,etc and a removable rear window.....well it got put in the modified class and we laughed and said so much for that award.....i talked to the judge when he came over to look at the car and pointed out all that we did.......well we won the award so i sent my son up to accept the award and the ***** judge wouldn't even look at him.....but we got that sweet award
I believe it would be appropriate after class determination to then deduct for items that don't comply with class. For instance, the Edelbrock carb should result in a points deduct if you are in stock class, no matter how crisp and clean it is. Sound right? So, be careful what mods you make if you are interested in winning shows. You should figure out which class results in the fewest point deducts, and then try to qualify for that class.
As mentioned above, all local shows are different. When you call to ask information about the show, ask how many mods are allowed for the car to be entered in a "stock" class. They will tell you if your mod can be placed in stock or mod class. I would be very surprised if they would not let you show as stock, if that is the only mod you have. [The rough 'rule of thumb' is that up to 3 mods are (usually) allowed.]
I do not think there is an answer to this question. Different shows have different rules of what differs between stock, custom and modified. One show I attended stated 7 mods to be in the modified class. Other show organizers look more at the visual - wheels, blower thru the hood.
The answer lies in what the organizers perceive as being a stock or non-stock car. You can go to 7 different shows and have 7 different sets of "rules".
That said, I have never been to a show where just the carb change was sufficient to move to a modified class.
Sanctioned ISCA shows, clearly define what is considered a modification, and what is Not.
IF your gonna chase the shows, get a Rule book and study it, select your classification.
then build the car to max. of that classification, thats how you win in ISCA.
typically 3 modifications will bump you into the next class.
As stated local non-sanctioned Car Shows, do not follow any offical rules,
its completely up to the guy reveiwing the car, and don't expect the the guy judging
to actually know what he is looking at either.... X - ISCA Champion
