I think that Extreme Street N/A and Power Adder should be allowed more transmissions such as th400 and th350. There are a lot of cars on here that run stock pcm,optisparks and stock intakes and weigh 3400+ but are forced to run Modified N/A and Modified Power Adder which can run Aftermarket pcm,carb and intakes and weigh 3100lbs. What do you guys think?

 

i dont think so

 

In the defense of the extreme street class the emphasis is on street cars. IMO and obviously whoever made the rules, a 3-speed auto isn't for a street car, is essentially 100% of the time installed for drag racing purposes and did not come installed on the 4th gen f-bodies from the factory. I think it's only fair to keep it with the factory installed 700r4, 4l60, 4l60E, and T-56 transmissions but I see where you are coming from. The rules are pretty strict for the street classes and they should stay the way they are because it's for "street cars" just IMO.

 

I agree with the second half of this statement, that street classes are made for that reason. The idea is you're retaining the "stock" feel of the cars. As for the first half, the 3 speed auto's were installed for decades in street cars. Long before they decided to try and put a 4th gear into an auto there were 3 speeds. Hell even a 2 speed was an option, and it was cheaper than the 3 speed. They were available for decades, and you could even order them from the factory with a 3.73 or a 4.10 gear. So for it to be "drag only" is not a correct statement. Take for example the 69 camaro's and 70 chevelle's. Both could be ordered with either a TH350 or TH400 and with your choice of gear. So much for drag only........

 

Every high eight to low nine sec car can probably run modified instead of outlaw which leaves people like me to wonder why go if I have no chance.
I decided on the TH400 for strength and I think it takes more power to run it then any of those transmissions listed in the rules. But if it is a class built for factory components 12bolts and nine inch and dana 60rear ends shouldn't be allowed either.

 

I am 100% aware of 3-speeds being put in several several several vehicles from the factory up until the 1990's even (1990 454 SS pickup last I am aware of, sure it may go beyond that). Anyways, you must have missed my point or else I should have been more clear...The 4th gen f-body did not come from the factory with a 3-speed auto and the only reason someone would ever put one in is for drag racing. Not talking about the past here were talking '93-'97 f-bodies. That is my opinion but I am sure that was the reason for them having the classes set up the way they are. I didn't make the rules, I just follow them.

 

I think you bring up a couple valid points with you having to compete with cars out of your league simply because the TH400 (unless you also have a rear drag bar?) and with the rear ends. In their defense there is hardly any chance a heads/cam or stroker heads/cam car thats a 6-speed could run a 10-bolt still. I still do myself but I am an auto. That's where I could see they grabbed that from and the TH350's and TH400's are stronger trannys but I've seen 4L60E's in the 9's so....Again just my guess to their reasoning, hopefully someone will chime in who was part of the rule making.

As for the 3-speed thing again, 3-speed autos these days are not considered streetable transmissions. Hell these days there are cars with 6 and 7 speed autos. Times have changed.

 

so you're whining because your car is too slow for modified... tell me what advantage a 9" will give me with my 6 speed, except for just being able to get down the track reliably and safely?

 

Believe it or not I do know more than my fair share of people that have swapped to a th350 only because of the durability factor. After blowing through 4-5 700R4/4L60 trannies, they swap to the TH350 and never have to replace it. Granted these were DD cars, they didn't drive very far. They were less than 25 miles a day to and from work (I drive 2 miles round trip to work and home....I'm a lucky one). Personally I would go to a 350 if I didn't like the idea of going fast with 4 gears and having the ability to cruise the highway at 75 and 2100 RPM. To do that with a 350 I'd have to have a ridiculously short gear. So not everyone does it to these cars for drag racing, but I will give you that's what MOST of them have on their mind when they do it.

 

I think only trannies that came in our LTX cars shoud be allowed.

 

A 4l60e is a great trans but it takes a lot of money to make it reliable for a 9-10 sec car thats why I went with the TH400. I still have the stock rear sway bar so the only thing holding me back from this class is the trans.

 

Yes it does unfortunately. I refuse to go 3-speed because my car is a street car but for a drag only car TH350/400 all the way. One day I will probaly swap to a 4l80E so I keep my OD and not spend a fortune with the 4l60E's. We'll see how long my current one lasts I have faith in it.

 

Tell me the advantage of a TH400 over a 4L60E? Not whining about nothing just trying to have some good close racing!

 

If you put the 4l80 in Ill see u in modified! Oh well Ill just deal with it! More nitrous here I come!

 

I would officially be the slowest car in that class lolol. If there were more cars it would be cool if they had the street class limited to stock displacement or .30 over cars with stock rear bars, stock transmissions, basically the rules they have now but limitations on the displacement. Then have a class inbetween the two like modified street/strip that catered to cars more like yours, larger displacement strokers with certain limitations that kept it out of the extreme class. Maybe something like stock style intake manifolds only, drag bars permitted, optispark required etc. etc. Unfortunately alot of cars would be needed for anything like that to work.

 

Not streetable, lol. I can hope in my 3 speed, go cruise down the highway at 75mph at 2350rpm, it's all about gearing/tire height, and I can still run low 10's.

That being said, I think the 3 speeds with no transbrake should be allowed in this class in my opinion. I don't see the real advantage of a 3 speed vs a an OD for this class. I've daily drove 3 speeds without a problem, and hell my 3 speed in my rx7 turns less rpm down the highway than my OD did in my close to stock firebird 5 years ago.

 

I agree with you 100%
Ill come out with it, I built(well still building) my car for this class. Going off the origial set of rules. Not I have to many goodies to be in the class, However if not for the tranny thing I still could on the N/A side.
IMO The biggest reason for the 3 sped was money. I bought a damn good Used ATI Th350 for less money than I could have bought a well built clutch for my old 6 speed. I evengot the convertor to boot. I understand that they didnt but them in f bodies but it isnt a stock class.
I thought extreem street was originally suppose to be fast *** street cars.

 

Guys, I beat this one to death last year. It ain't going to happen. The only reason I put in my th400 was the strength factor. When I did the swap, no one had a reliable 4l60e running deep in the 10's. When I say reliable I mean one that does not have to be rebuilt every year. I drive mine on the street, I drive it to work (20 min. one way), I drive it to the track (40 min. one way). I support Tony and the gang on what ever rules they set up, but I feel this one is a bit excessive. Not that my opinion matters much, because I am still minus a tow rig, so I have yet to make it to an event.

 

The whole point of the ES classes were to give the guys who don't have full blown drag setups a chance. Just because you can hop in and drive it down the street doesn't make it valid for these classes. If that's the case you might was well let Taner and Tony in this class, right? So if we let in a TH350, what keeps out the guy with a glide? Transmissions, interior, suspension, electronics are limiting factors for the ES classes and that's how we keep the competition close.

 

Yeah, because there are so many LTx guys with a glide still fitting the rest of the rules of this class. I thought the stock intake, 23 degree heads and stock pcm where the limiting factors in this class. 2 of those things Tony and Taner do not have.
