Tony and Taner both have 23 degree heads. I don't know what you're talking about. Just the intake, and PCM but that wasn't my argument. I was just saying that simply because you drive the car on the street doesn't make it a valid argument to fit in 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.
Just want to throw out that I think the street class is limited to a 26" tall tire. Your right, the right tire size and gear can make it street friendly but everybody I know with a 350/400 in an f-body isn't even close to being street friendly, chances are they weren't trying to be in the first place. This could be argued all day lol IMO I feel they should only allow the transmissions that were put in the cars in the first place but I do see where you and some others are coming from considering there really is no advantage of a 350/400 over 4l60E. Actually aren't the 350/400's a bit heavier?

ES is limited to a 28" tire. A TH350 is the lightest of the 3 autos at around 130 lbs. TH400 is next at around 140 lbs and the 4L60E is around 175 lbs. So, no they're not heavier.

Thanks for clarifying I must have looked at the wrong class rules. Wow I had no idea they were actually lighter, I have always heard that the TH400 was heavier and TH350 I was never sure about. I need to start questioning my sources of information

I think that 3 speeds should be allowed but no transbrakes. There are some people who drive their 3 speeds on the street. But it order to keep it fair with all of the 4L60E guys just keep it footbrake only.

many ppl leave better and harder without the brake. i agree with not allowing it. although it sucks for the few that put it in for strength if it was allowed for you guys itd open the door to alot of guys that put it in for racing and hav a racecar that fits the rules of a street car.

Yes I was refering to intake and PCM. Those are the real limiting factors imao. But like I was saying my opinion doesn't count. You guys do want you want. You are the ones putting this together. If I can make the next event I will.

I agree on the brake thing. My tranny has one but Im sure there is ways to diable it and still able to run.

i guess its not an advantage to have a rmvb, lightweight non lockup converter, better first gear, lighter trans weight, etc....

Exactly, so what is the advantage of using it over the 4l60e?

How does a rmvb make the car faster than a 60e? You can get a non lockup converter for a 60e so that doesn't matter, and the 60e has a STEEPER first gear to allow a better 60ft. The 3 speed is lighter, but with a weight limit it that shouldn't matter either. So again, how is the 3 speed such a huge advantage?

I like the arguement about 9"/12bolts/etc, people are adding steeping gears(less driveable like a 3 speed since so many people think 3 speeds are not streetable ) and doing it for more RELIABILITY. Not because they give a big advantage, but because they make the car more reliable, same as throwing in a th400 in my opinion.

Oh I should also point out my 3 speed cruises less rpm down the highway than my stock geared TBSS. Maybe it isn't streetable either.

FWIW, Stock Eliminator classes allow other transmissions.

I have put my 4l60e well into the 9's at 3700 lbs. raceweight. They will hold up .

who runs a non lockup converter in their 60E? rick in the Ai racecar? dont bullshit me, you know the steep first gear is a liability if your car is making any power, or, like youself running around in a 2500 lb car. my stock t56 isnt going to hold up very long, but im not running out for a liberty or jericho trans...

We all know no one could possibly run faster than a 10.0 on a stock-style transmission. Oh wait...

the point is that you can run a non lock up converter, every advantage (other then less physical weight) that the TH400 gives you, the 60e can give you as well

aside from the better gear split of the th400 and th350 over the 4L60e, what advantage do they have in performance? aside from being able to make it through a night of racing without junking out.

no different than a 6spd car running a 9". what performance benefit does it have over a 10bolt, aside from being able to hold up to a 6k launch on slicks?


if you allow a non stock (and even a non-GM) rearend in the car, why not allow a 100%GM tranny, with a stock valve body?

You guys have a bunch to learn about transmissions!

1. The TH-400 can be built so that it robs less HP than a 4L60E.

2. There is a huge advantage to be had by running a 3-speed if you know what to run.

3. I have seen mild gains running a RMVB in some transmission applications.

4. There are a lot of different gear sets available for TH-350's, etc.

5. If you were to open up the transmission rule a smart racer could pick up as much as three tenths over a 4L60E with your average 3600-4000 converter.

Just my two cents, but allowing non-stock transmissions could change the character of this class. Come run Mod N/A!
