moonflow where in the world r u getting your info from Lm counts are definitely down a couple weeks ago had 10 Lm's
Are we seeing a trend

I couldn't agree more with the Hoosier tire rule!! We run a street stock and the biggest killer for us is the $125 a piece tires yes we can buy used and we do but by the time u get a used tire there isn't much left of it. Correct me if im wrong but isn't the street stock class for the guys that are just starting into racing and are trying to learn how to drive a car or the guy that doesn't have thousands to spend on a car but wants to race? And I don't think there are many home built cars anymore which is disappointing to me because that is what that class is all about. I have brought several of my friends to the tracks over the years and there's biggest turn offs are wow how many of these open cars are they going to run ( Because they can't tell a difference between the a's and b's) and they also complain about not having a variety of different cars in the ss class they all say it gets borring watching a bunch of gbodys go at. Which is that way because of the rules. The rules are pretty much ment for a Chevy gbody they let the guys run a Ford 9inch and the carb rule hurts the fords beacause they can't use a holley even tho Ford used them from the factory the biggest carb you can get for a Ford that isn't a holley is a 412cfm carter. Where the Rochester are 500+ c.f.m.. If they where to change those two rules I think they would see an increase in ss car counts with a better variety of cars. But that's just my opinion and what i have noticed based on some feed back from my friends

I've never figured out why they require the use of the "factory" carburetors in the street stock class. Why not just mandate the 7448 or 4412? A tech legal Rochester isn't going to be 500+ cfm and Fords generally came with the Motorcraft never a Carter. The Motorcraft is a very good carburetor design and it could be way superior to the Rochester except for the fact that they ALL came with a very large annular style booster that takes up a ton of room in the venturi. Even a cluster from a 4010 Holley is still an annular which hurts air flow knocking it down to the middle 400s or so. Another serious problem with the Rochester is that the really good 1 3/8 cores are nearly impossible to find and can be very expensive. Jet and some others sell 1 3/8 carburetors that are really bored out smaller ones and not the same at the real 1 3/8 cores.
Having a cast iron intake rule is also ridiculous. I built an engine for those rules some years ago and I managed to find about three candidate intakes to use for testing and flow work and that wasn't easy. Why not simply mandate an inexpensive aftermarket intake like Allied did with their very well thought out Sportsman engine rules package. It is a shame that class isn't doing well because it makes a lot of economic sense.
You are correct it is. A motorcraft idk why I said carter. And the intake rule is more of a weight thing I think because you can get a pretty much stock design aluminum for about the same cost. The biggest deal with the rules is of you are going to run anything but a gbody you are at a huge disadvantage. And I'll be honest I don't know much about gm stuff but I've had several guys tell me that the Rochester can easily be 500+ c.f.m but thats all I know is what I've been told I've never messed with them. And idk what a Rochester cost but I know a 4412 will cost you $500+ which is a bit much for a for a street stock.

I've seen these type of post on here every year for the past 5 years and frankly I will see them for the next several years to come. I moved to Gulf Shores Al. almost 2 years ago...Car counts struggle down here to and Late Models are gone...Modified car counts are maybe 8 on a good nite. Streetstocks maybe have 12 to 15. purestocks maybe the same 12 to 15 but the stands always seem to have a good crowd... When the Nesmith Streetstocks special races come down here the Stands are packed... One would think it was a world of outlaw race. Down here they pay a 1000.00 to win in the Nesmith SS, Regular Streetstocks and even in the pure stocks. We have ventured over into Mississippi and the Nesmith Crate Lates and Nesmith Streetstocks have packed the house...I do miss watching Rusty Griffaw, Dean Hoffman, Bobby Bittle and the rest of the talent "to many to list" that has raced at I-55, Tri-City and Belleville. Money has killed the sport !

It isn't smart to get too caught up in flow numbers when it comes to carburetors. Fuel curve even in a restricted application is generally more important than reasonable differences in air flow. The same can be said about WOT torque and HP on the dyno vs proper part throttle drivability factors which are more important and again fuel curve related.
I would think that the rule requiring the Rochester on an iron 2V intake came about with the assumption that the racer could go to a salvage yard and get those parts which is very difficult to do now.
It is sort of like allowing a quick change rear end in a modified. It costs more than a 9 inch rear but if you're planning to run at several tracks and are willing to sacrifice some horsepower it is probably less expensive. Stuff like this is what makes writing rules to attempt to save the racer money very difficult.
There is a lot of monkey see monkey do in racing and while I have not plotted one I've wondered if something like an early '90's Crown Vic would be as good as or superior to something like a GM metric, could be...
Mud flow is right year after year this is talked about but no changes are made. I use to be an avid fan going to the track every weekend. But now I seldom go because of finances and the same guys winning all the time. I live in highland so I go and sit on the hillside to see who is in the pits. to me some one needs to run something different there are to many tracks running the same classes not enough cars to go around. I like watching the micros but not very many come to highland. I wish I knew what the solution is because it is a sport that I love and I can't stand it fading away. do we run tracks every other week? like one week highland one week Pevely? with 1 point fund? I don't know but something needs to be done
