I had a similar problem with a Duster, RMS adjustable upper control arms was my problem solver.

This has been a great thread as I am looking at the same issue for my Duster. What size tires are you running front and rear? Rear shocks? Thanks.

I had the same issue on my Duster with a 383. Used copper pipe and fittings, soldered the joints and have been running it 2 yrs with no problems.

I'm kinda having the same problem with my 383 Duster. I can drive around town all day at 190-200. As soon as I hit the highway temp shoots to 230+ and I hear water gurgling in the heater core. I'm wondering about that 'water moving to fast' theory. I'm running a 190 stat and a 3500 cfm electric fan.

Ok gents here's an update: bad spark plug! Even though they are new, been in just a month or so it just kept running worse and worse. Started pulling plugs and behold! Wet plug on #3. Changed it out, set the timing to 12* initial and Woo Hoo! Runs better than ever. Any recommendations for...

I checked the timing chain when this all started and there is no slack in it. The distributor and ignition box are new, just installed it yesterday. The thing that bugs me is that it used to run great, makes me wonder too about a weak or broken valve spring or some other issue with an intake...

It will backfire at higher rpm when moving or just winging the carb. Didn't used to do it, in fact it ran great. If I bring up the rpm's slowly it's fine, but try and spin it up quick and it pops. The only thing I changed before this started was new plugs and changed out the Thrush glass...

I have a 383 in a '71 Duster and I can't seem to figure out why it sometimes backfires through the carb during hard acceleration. The motor was in the car when I bought it so I don't much about the internals other than it had a "soft rebuild" so I'm assuming it's pretty much stock and was just...

Added the vapor return system that you outlined in another thread...so far so good. Had her out twice since installing for over an hour each time and not a hic-up. Thanks!

Ok, here's my problem. '71 Duster with a 383, 727TF stock 4bbl intake and Summit 600 carb. Ran great when I took it to Good-Guys in Des Moines a few weeks ago. Now it will start fine when cold but at temp the fuel will start to disappear from the clear plastic filter then it dies. Happens on...
