can a 833 23 splin hold up to over 800fpt & 900hp - 01/27/13 03:34 PM
OK this not a race car, this is going to be my 4sd muscle car. But I will take it to track sometime. I have a 402ci with an F1 on it. I did Dyno the motor but that didn't go well. But at 5100rpm it did make 776fpt and 754hp running sickly. So once we get her rite 900hp should be no problem. So how do y'all feel about me running a 833 4SD?

On the street you won't have any problems. At the strip, that's another story. If you plan on "dead hooking" the tires, the trans may last a few passes, but will eventually break, if something else doesn't break first. What clutch are you planning on using? What rear are you planning on using? That kind of torq and HP will need a good clutch assembly and at least a Dana out back.

I think that you would be pushing it to the limit with an 18 spline box. The 23 spline setup has a finer tooth setup on the gears. I don't think it is going to have a long lifespan in back of your powerplant.

There is absolutely no way...I think even on the street, with any kind of spirited driving, it will be short lived.
If you plan on keeping it stick I would seriously be looking at a trans from liberty, jerico, or G-force...or step up to a nice Lenco and never worry at all again

This is what will happen, first to second gear will go smoothly, shifting into third under power will be something that will make you cringe. As the input shaft and output shaft come together at the third gear it is a week point in the transmission. The pressure will push the gears apart and destroy the main third gear and cluster gear if not more. Ask me how I know that with a lot less horse power. Liberty Gears told me that would happen, took me 3 times to figure out. Spend a little more on a good transmission now and you will be $$$ ahead.

another option is a Tremec 5 speed (the rpm's at 80 with 4.10 gears is 2500, the 6 speed is overkill)
there is a thread here
https://board.moparts.org/ubbthreads/showflat.php?Number=5899467it requires major chassis mods including modifying your torsion bar cross member as well... not for the lighthearted

That still won't be enough in my opinion...with the power he plans on making, a tremec of any kind will be on borrowed time... Massive amounts of power will require race type gearboxes and a GOOD clutch
Sure its only a street car that will see the strip "sometimes", but all it takes one pass to have an expensive mess of parts at the power levels he is at

You should just get it over with and put a real trans in it , or buy as many A body 833's as you can find ...

Just run BF Goodrich TA's and you'll not likely ever hurt it.... Of course now 650 of your 900 horses are just there for making tire smoke.
Would a Richmond 5 spd even come close to hooking that up? It sounds to me like you will be in the 800 ft/lb range when you get it tuned and torque is the great destroyer of drive train parts.

Hey Kevin, I was told torque do destroyer parts, that is what I'm scare of. Now here the kicker so don't laugh, I was going to use the od 4sd on the street and the regular 4sd which I was going to let Liberty face plate and use a v-gate shifter at the track.

833OD? 
(sorry had to laugh)
I know a guy that runs an 833OD in his Hemi RR with no troubles BUT he doesn't beat on it and by that I mean no drag strip launches or power shifts and OD is for cruise ONLY. He runs it up to whatever in 3rd and holds it there in OD. If he needs to accelerate from like 60 to 80 it's back to 3rd to do it. He has driven it from Canada to Florida several times.
Your right foot will ultimately determine how long less than ideal parts will last.

If you want to do it safe and be able to use the hp you have it seems that either a Lenco, G-Force, or Richmond is going to live (from what I have been told by vendors and users alike). There are ups and downs to each setup but the Lenco is by far the best bet for low maintenance. I am in a similar boat (the 150 less hp than you boat that is) and have been making lots of inquiries lately.

Show us some pics after the 833 OD splits the case in half.
..seriously - w/o bushing those cases for the countershaft (if its aluminum) you ain't got a chance of that thing living, 318's and slant sixes can kill an OD 833...

Re: can a 833 23 splin hold up to over 800fpt & 900hp - 01/28/13 11:24 PM
I agree with JohnRR...how much did you spend building that 900 hp small block?
and now you can't afford to put in even a $2,000 transmission? a TKO-600 would be better than a 23 spline in my mind, but even better than that would be a viper spec T56, as there are guys with Vipers that are into the 800 hp range and doing ok on the viper spec gear box.
but even they say once you put twin turbos on the viper and push it over 900 hp, that the T-56 is no good.

A 18 spline 833 would be marginal with a stroker if you did not have the blower on the street let alone a 23 spline. I used to break 23 splines with a 340 and dot drag tires. The only way that trans is going to live at all is if you never get on it. I would not waste my time breaking a good trans. Take your time, save some more money and do it right. Whats the use of building a 900 hp car if you can't get on it?
I would break it the first day I was driving it.

As long as you run some real greasy tires and never get it to hook you'll be fine.
HP and 4 speeds are fun plus you'll get a good workout pulling the trans to replace the clutch. How often? That depends on the right foot ...

The newest T56 Magnum 6 speed is supposed to hold up to 900 horse. You can get one brand new for under 3 grand. It will take some fab work to install it.
Like Tom said, breaking driveline parts can be dangerous. Don't risk your car and your life and health on parts that are not up to the job. Make it as bullet-proof as possible.

Radials don't play nice with stick cars! Got to go Bias Ply.
Just to state the obvious,....Don't build a 18K power plant / $1K clutch infront of a $300 transmission.
You need way more trans. Sell the clutch (23 spline) and get the right setup to hold up to your power / chassis.
I've raced with 550 hp and 23 spline, but now I've gone up to 18 spline. If I had 600 hp or more, I'd be looking at the $2k to $4k transmissions out there.

If you ask the question and several give their opinion, and they're good guys who know their stuff, why would you dispute the consensus answer? Wishful thinking?
We need Roseanne here to tell you, "Get Real!" It doesn't take a $18,000 engine that makes 900 hp to have a muscle car. Back in the day, people in my neck of the woods ruled the street with Swinger 4-speed 340s with 3.91s. That was when the "muscle cars" were new. A SS454 Chevelle or a Road Runner with a 440 swapped into it were kings of the street with their 350 flywheel horsepower. Now in other parts of the good-ol USA, street cars were getting into the 450 hp range, but that was about it, and those guys were more street racers than anything else.
I'm talking abot 1968 - 1974. '74 was about the end of the muscle car era.
In 1977, I could have bought a real Yenko Camaro for $2500. My friend bought a 1968 SS396 Nova 375 hp with close ratio 4-speed and 4.11s in the 12-bolt for a little under $1000 from a dealer who had stupidly taken it in trade. Gas was up to a buck a gallon and we all knew the world was going to pieces.
That's how it really was.
R.

Make sure you get a good adjustable pressure plate type clutch (aka slipper clutch) to protect those expensive driveline parts. Tim Hyatt of Hyatt Racing can get you set up 440-254-1311

I will chime in, 68shifter posted above. I can give you the lowdown on his car (mostly), 600-650 hp, 3200 lbs, slipper clutch. 20-30 passes on a transmission. I've attached the picture of 3rd that he broke, face plated, cryogenic processed, ..etc.
Has a G-force now. Only broke that once...

What was the g force rated at? When the g-force broke was it driver error or ? And how do he like his g-force tranny? When I talk to them yesterday they offer me the 5or 6 sd rated at 1000fpt. Is this the same tranny he have?

You won't break this one.
Available in junkyards everywhere. Depending on the torque rating, 1250-2050 ft/lbs $1000-$4500.
Floor pan will need to be cut of course and with 13 gears you may need to work on your shifting game.

I don't dispute anyone's experiences. But how did anyone ever race Pro Stock in the 70s? Be it GM or Chrysler they were coupled to a 833 trans back in the day. Along with inferior clutch technology of that period it's amazing that Ronnie Sox ever finished a race.
Just asking, how did they do it?

I have have no doubt that those transmissions were coming out for refresh or being swapped after every event or even possibly every couple of races.
