I originally set my 69 Satellite up to be more of a drag car, but since then I have decided that I would rather have it handle better since it is mostly a street car. I'm also becoming more interesting in the pro-touring type stuff. I like the idea of an old Mopar that can handle like a modern sports car. What I have now is no sway bars, 318 t-bars, SS leaf springs, fully rebuilt front suspension, Dana 60 in the rear w/ 4.10 gears, factory manual steering box, and Comp Eng 3-way shocks all the way around. Motor is a 600 HP RB-based stroker w/ aluminum heads and 727 w/ 3500 converter. Right now it handles like a boat. My funds are kind of limited right now so I'm looking for some upgrades that will make a difference, not break the bank and something I can build on. I'm thinking a good front sway bar, the Firm Feel stage 3 box, and maybe some 1.03 torsion bars. Possibly some new shocks if the Comps won't work. I am about to order the Dr. Diff rear brake kit to go with my SSBC front kit as well. Let me know what you guys recommend, all input is welcome!

You're on the right track! My car was in almost the same situation this time last year. My first upgrades were a Hotchkis front bar,replaced drag shocks with just 17$ monroes and even with big'n'littles it was a dramatic improvement accross the board. Then went with 18" wheels and tires and ditch ss springs for ct springs and its a completely different car waaaaay more fun to drive and I'm far from done.
Mopar to the bone!!!

You've got a good plan especially with limited funds. 1. Front Sway Bar 2. Larger torsion bars 3. Firm Feel Stage 3 box. - If you hate the standard Chrysler power steering, then yes this would be next. I'd skip any changes to the rear brakes, but if the fronts are drums, that might #4 on the list. This depends on how well you've got the drums tuned in, your driving style, and location. It sounds like you may have already bought a front kit, so then its done, go with it. As far as shocks, see how these work out and what you can do with them. After those, the next and arguably most important item, is tires for projected uses. BFG T/A and Firestone Indy 500s are Ok on the street and even in snow and on unpaved roads. But there are better options for dry pavement that trade off the versatility. Also check out Where to Start: A Reading List

Not sure what the budget is, but I'd say do it in this order;
alignment - You may have the DC recommended drag alignment so you'll want to change it a bit. Set it at desired ride height, as much positive caster as possible, 0 to -.5 degrees negative camber, 1/8 to 1/16 total toe in. This may be a bear with manual steering, but will improve the car's cornering manners. The need for power steering after this will be a personal preference.
front sway bar- the need for this is a no brainer. Figure $150 for a solid bar, $300+ for the tubular Hotchkis
shocks - shocks are to the suspension like a cam is to an engine, important to defining operation parameters. Your CE units can be dialed back to 50/50 for now, but then step up to some real good units, like the Bilsteins $300-400
t-bars, step these up if you want to firm things up further after feeling the results above. $200 on sale.
firm feel box - Unless it is really killing you with the alignment, I'd wait until here to install it. The box itself doesn't improve handling, but it does improve your feel. $300+ for box plus you'll need pump, brackets, hoses. rear springs - SS units have too much camber, plus more rate than you would want with a rear sway bar. You'll need to flatten them out with a more OEM XHD like configuration. Maybe pull a couple of those half leafs out and see how that changes things. free - $200
rear brake kit, skip it altogether. No need to rear discs unless you're road racing it regularly.

I would skip the rear disc brakes, money is better spent elsewhere.
I have run ffi sway bars and other components, you can't go wrong with their stuff.

The search function here is terrible too so it's hard to find specific info.
There are two search functions, one in the bulletin board and one powered by g**gle. Agreed they're not the best but I've used worse. One reason you are not finding specific info is that there is no one size fits all, especially for a vehicle that is multi-purpose.
You can probably sell or trade the manual box. They're adjustable and rebuildable but some have a bushing type bearing at the bottom. I'm sure places like FF can and do machine them. For your car, go power steering.

The brakes on my car are terrible right now. I have SSBC 4 piston manual brakes with a 15/16 aluminum master and 10" drums in the rear. Car won't slide the tires on gravel. I have a drum/drum dist block and no prop block.
If you get stuck on this probably best to start a seperate thread either here or general tech section. Yes the lack of prop valve will be a problem. Beware that the factory had a variety of arrangements for disk/drum. Residual valves and proportioning were located in various places depending on year and model. So you need to do some investigating but its not that complicated.
Unless you're running a brake lining that needs heat before it starts to really work, you're right that something is wrong. Bleed, adjust, check. If there's no proporting valve those drums should be locking up first.
Now, as to valving, here's what you need to have: Residual valve: Somewhere in the system going to the rear brakes there should be a residual valve. It's small, and acts a partial check valve. Could be in the distribution block, could be in the master cylinder front resevoir outlet. Maybe elsewhere - I won't pretend to know all the variants especially on B-bodies and late models. The residual valve helps counteract the return springs. Proportioning Valve: If SSBC did not have a matching one they supply, and maybe they can't due to the variety of combinations, buy a little adjustable one, and place it in the rear line. Early a-body factory ones were adjustable, later they were incorporated into the distribution block. As above, there were probably more varations. However, based on what you wrote, I don't think there isn't one in your setup. Buy an aftermarket one and install.
The easy way to install the prop valve is to disconnect the line to the drum brakes and gently bend it or loop it to the exit of the prop valve. Then use a short double flared line from the parts store to connect from the distribution block to the prop valve. Another way it to cut and double flare - but most people find double flaring difficult.
After all that, you may decide you want power assist since drums are self assisting and disks are not. But first get it working, then you can decide if you like the feel.

I will definitely do the sway bar, what brand do you guys recommend? Size? Do I need a rear bar as well?
The torsion bars, from what I've read so far is that 1.03 is a good size that will give good handling and not be too stiff. What is your guys experience with them? Am I on the right track?
There are some recent b- body and other sway bar threads in this section. I think you'll find good guidance in them.
Here's one https://board.moparts.org/ubbthreads/show...e=1#Post7063919
Some folks say you can't go too stiff on a t-bar, but it comes down to the overall package. If the front of your car is around stock weight and there is no significant chassis stiffening, then around 1" is probably a good start but anything down to .93 would probably feel better than what you have now. Also, most (but not all) SS spring rates are around 160 lbs/in vs. 110-130 lbs/in typical of standard and heavy duty factory springs. So with that factor, I would not hesitate to pick a t-bar in the high .96-1.03 range.
After you've made your first set of changes, then you can play with the rear springs as TC suggested. Other options are to see about dearching them or (low buck) moving the spring eye up, or short lowering block. No love for any of them, but you got to work with the constraints you have.
Heh. Looking again at your photo, I see unpaved is a part of the road terrain. So both too stiff and too low can become an issue. Before lowering the rear, see if you can get the front down to factory specs before you start realigning per TC's recommendations. To a small degree the rear will drop when you do that.

Thanks for the help Matt. I think I will go with the FF power steering, seems like everyone loves it. I do prefer power steering, but the box I had on there before was so over-assisted that it was almost scary at highway speeds. At the time I had no idea about the FF box so I just ditched it for the manual box. I was thinking about just buying a re-pop 69 distribution block and the factory prop block for a disc/drum car from Inline Tube. Does that have the residual valve built in? I did get a prop valve from SSBC but I didnt use it and now I can't find it. As far as the power brakes go, I have too much cam, so that's not an option. I tried it before, b/c the SSBC came with a booster but it didn't work very well. I do have a set of 11" brakes that I can rob off my Duster project if it would help. I can use the disc/drum dist block from it as well. From reading the thread about the sway bars, it looks like there isn't much difference between them. I looked at the bars from Summit and they look good, price is right too. The instructions looked pretty straight forward, I may go that route. Should I get the rear bar as well? I was looking at the Just Suspension and the PST torsion bars, the price looks good on both. All my front end parts are from PST so I may just get the bars from them. I've had good luck with them so far. The gravel in the picture is at my father-in-laws shop. He has about 20+ Mopars in that building there. The ride height is about is low as I can go with the SS springs. I have 2" lowering blocks on it right now. The tires are also very tall at 29". I would rather do away with the block and throw some flatter springs under there but that's what I have right now. I was also looking at some shorter tires, maybe a 275/60 15. Right now I have 295/65 15's. Again, thanks for the help.

Generally residual valve would be inside the front fitting on the master cylinder but I really don't know. Could be in the prop block. I don't know the specifics of the '69 B. Someone else might and the remanufacturers ought to. There's some good factory technical service information at the imperial club. Scroll down to 1969 and check out '1969 Service Hightlights' for the brake changes instituted that year. Then check out the other brake specific bulletins. Let me get this right, the car has the 10 x 1.75" brake drums on the rear or the wider ones? In either case, they should be stopping the car at low speed. The wider ones would be better but whether 11s are worth the wieght is questionable. Bigger brakes will help dissapate the heat but there is no heat being generated so that's not the issue. Most lining materials work better as they get hotter but they all have optimum ranges. Street linings work from dead cold (even in the arctic) to at least a few hundred degrees. Race only compounds work from from a few hundred degrees to glowing hot. So those are the extremes. In the repeated high speed braking that occurs on a road course (or an oval) a lot of heat is generated and needs to be removed. No rear bar at this time. Unless you've shifted a lot of weight to the rear, this car needs more front roll resistance. Adding a sway bar to the rear will increase the rear roll resistance that already is relatively high compared to the front. As a result you're getting into the possibility of oversteer situations developing at high speed. There was a discussion on oversteer not long ago in this forum - search function should turn it up. Well I know tires (and wheels) are not cheap, but you can play with ride height that way for sure. I use a a 'tall' 70 series tire on the street (actually close to stock diameter), and a short 50 series tire on bigger rims for autocrossing. For the time I did a rallycross, I cranked up the t-bars a bit and used the street tires. One advantage of smaller diameter tires is you may save weight.

Didn't mean to be confusing. 10 x 2.5" drum is stock for the '68 Bendix equiped disk brake cars. That's fine. A larger drum adds unsprung weight and more rotating mass but might be worth it if you were repeatedly braking from 120 mph to 60 mph or even 80 to 40mph.
When I was describing temperature ranges this was in reference to lining on the pads and shoes. A stock type lining is fine unless you start doing road courses. Obviously there are different qualities in lining material as well as backing plates so later on you can try different ones if you want.
Anyway, whether or not you change to larger rear brakes, it sounds like the system is not working well and needs to be dealt with. That's my main point. Without a proportioning valve, the back drums should lock up when you hit the pedal hard at low speed on gravel.
Locking up the rear first is not good, especially in the rain. Therefore, you got to get the proportioning valve. If you stay with the stock rear brakes, a stock valve should work fine. think Andy F has a new book on B-body upgrades, and it may be helpful in these matters. I haven't seen it so that's all I can say. There were also some magazine projects involving b-bpdies if I remember correctly. You can check the Where to start reading thread for those.
Drag radials. Well think about a pair of tires and rims that match the front. Then put the drag radials on just when you're going to the drag strip. See how things feel with the changes. Save a major tire and wheel change for later when the tires are worn or getting hard.
Not sure what you're looking for in sway bar info. Biggest variables are diameter and attachment methods. Next is how thoroughly they tested fit on different combos. Finally, you may find some bars are hollow which saves weight.
Andy's book or maybe Tom Condran's old book may have some specific combinations they recommend. Otherwise, the best we can say is you're in the right ballpark with your plan. Then you can get more into tuning and adjusting it, if you want.

It takes a few minutes to look through them all, but check out the following threads on THIS very forum: * What suspension mods are in your B body... I started that one. * The suspension mod register at the top of this page. * Anything on sway bars, also on this forum. The stuff that you have outlined sounds pretty good. The rear discs can wait. I put them on my car at first because the 10" drums were out of round and needed new shoes as well. The disc rotors looked better through my wheel spokes too. Some newbies can appreciate the "package" approach when setting their cars up for handling, because it takes the guesswork out of the job. It also takes a large bite out of your wallet. Those kits often include a full front end rebuild kit, shocks, sway bars front and rear, leaf springs and hardware. Others also include frame connectors. I started out with a custom 1 1/4" front sway bar, 1" torsion bars and KYB shocks in front with Mopar Performance leafs, 7/8" rear sway bar and KYB shocks. My Charger kicked the tail out too easily and felt too squirrelly, so I pulled the rear sway bar off. It rolls and leans a little more, but it also handles predictably. Keep us informed as you make improvements. I think that you will like the Firm Feel steering box. If your exhaust system allows, consider adding the fast ratio idler and pitman arms. Those make the steering react quicker, add stiffness to the feel of the steering and reduce your stering wheel turns from 3 1/2 turns to about 2 3/4 lock to lock.
