I have a stock chassied 68` Plymouth b-body,manual steering 4.5in wide rims on front and 215/75 Radials,rear 8in rim 295/55 MT radials. It is a real handfull if you apply any power. It will run high 11`s an makes alot of torq. Its not wheelspin its more like you turn the wheel and nothing happens. I will go so far as to say I feel its un-safe to play with on the street. Steering feels VERY heavy and un-responsive. All hardware is tight,toe1/8th in. caster unknown. On straight roads tracks true,no problem but plows in corners like it has a spool. I`ve tried 3-steering boxes and aligned it multiple times ,no improvement. I had a 69` GTX for a long time just before this 68` and it had the identical tire wheel package and all the same equipment except 4sp.. It handled well for a large stock heavy car. You could hang the tail out power-shifting down the street with one hand on the wheel and never worried about it getting away from you. This car is an auto,and I would`nt dare let the tail get loose, I doubt I could control it. Where do I start?

They can be set up to handle very nicely. A little more info on your stqarting point would be helpful in getting specific suggestions on how to get there. Engine, T bar size, sway bar (?), shocks, any chassis mods like frame connectors would be a good start.
Ok,I`ll go measure the bars. Shocks-- blue ones probaly K-Mart LOL 440 with 174 B&M Supercharger. Yes has sway-bar,need to measure that too. Chassis STOCK no-mods. 68,000 never wrecked or rusted original paint and metal.

That sounds like a fun car. Are you wanting to stay with that tire and wheel combo? The shocks are probably Monroes if they are dark blue. Sounds kinda like the steering is loose or sloppy?
Mopar to the bone!!!

Torsion bars .910 Sway bar .940
Nothing loose that I`ve found.

Bigger T bars and front sway bar would really help handle the weight of the BB + supercharger. A 1 1/8" sway bar, a set of 1" T bars and better shocks would make a huge difference. I used Firm Feel stuff and can recommend it... good quality and helpful advice.
Also, frame connectors recommended - not only to stiffen things up to make a good foundation for the better suspension pieces but also to help keep your strong engine from cracking the unibody.
On shocks, lots of (strong) opinions. I am happy with KYB's and 1" bars but no doubt the more expensive Bilstiens are better.
For the alignment, some negative camber and positive caster halp a lot. I set mine up with .75 deg negative camber and 5 deg positive caster using tubular upper control arms. With stock parts, a degree or two positive caster and maybe .5 degree negative camber is as much as you can get. Still better than OE settings.
PS: If you want to do this in phases, the bigger sway bar and alignment alone should make a noticable improvement. Then shocks, then T bars.

4.5" rims cannot have any decent sized tire on them. That is part of the problem too. Remember, traction is limited by the weakest link and I'll bet your tire choice is one of them.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Yeah, that's what I was thinking. You can have a big sway bar and T-bar, but if the tires can't grip the road, what good will turning do?

OK,Thanks for all the input. I see I don`t have enough info/facts about what I have to answer all the questions properly. Soooo, I need to do some more homework and make sure I have what I think I have. There may be an issue I`m totally unaware of. If I had never own one like this I would be less unhappy,but again the GTX was nice to drive. This car is going to end up in a field.

Like I said the GTX had all the same stuff and drove great. The steering is heavy and unrepsonsive.
This combination, while not a great handling set up by any means, has a feel that the owners feels is worse than an other similar set up. So we aren't trying to make it great, simply get it to a point where it is the same as another similar set up. I agree with the original post, all these same parts set up the same way should feel identical to the previous car that had this set up.
This, I think, is the key to it all - Heavy and unresponsive steering. There is something to the combination of pieces that make this car feel this way compared to the previous car. Heavy would make me lean towards a differing alignment spec. More postive caster will do this compared to the stock, negative caster specification. Unresponsive sounds like a worn out component somewhere.

Just wondering... was the GTX a manual steer car? Was this a manual steer car always? If not what is the box off from? Six cylinder cars interchange but IIRC use bushings not bearings, could be binding. Have you had the box apart? Has the adjusting screw been turned way in? Right off the top of my head (don't mind the reflection) I am wondering if the problem isn't in the box. Another thing, even old time alignment specs were different for manual steer/power steer, neither one optimal for todays tires. Jack it up, weight on lower arms, check for binding in steering linkage. With your tire combo it won't be carving any canyons, but shouldn't be terrible in normal/fun stuff. (Sideways... )
It takes gasoline to interest me.

Don` t know about "power steering as std. equipment" on a 69` GTX. But I did make some major progress on the 68` in question. 1st. steering was 1/2 turn off,meaning had 1/2 turn more to the right then to the left. So adjusted tie-rods and got that even. 2nd. caster was set at max possible,don`t know what it was but I adjusted it myself and that helped ALOT. 3rd. set toe @ 1/8th IN. Drives nice,steering light at speed,does`nt try to put you in the ditch w/power anymore. Thanks for all the ideas and advise
