    Mechanical Diode Converters?

    Just had a local guy rebuild my 727 to go behind my 99% street driven 440 With 520hp and 535 ftlbs as per the dyno. He wants to sell me a converter he has. 245mm with billet back cover, furnace brazed with mechanical diode, low stall stator. To be honest whats required in a performance...

    Worth the effort?

    Basis of the question is after getting a 2nd and 3rd opinion my year old 3000rpm advertised.recomended convertor will only flash around 2500rpm and is the cause of my gutless off the line performance. Now the 727 in the car is in good shape iternally BUT many of the holes in the case are...

    Precision Performance Products Shifter

    Looking at replaceing my Hurst Pro-matic 2 in my Duster with either a Cheetah SCS or the PPP Kwick shift. I've seen the install and hook up pics of the Cheetah but can't find anything on the PPP. Has anyone here run them? I HATE the adjustment on my Hurst which is why I liked the 727 sized...

    Lazy Shifting

    Vehicle is a mostly steet drive 71' Duster with a mild 340. The car has all it's kick down linkage and a transgo stage 2 shift kit but I have never cared for the way the car shifts. When cruising it's picky about the rpm it will take to attain 2nd or 3rd gear which on a residential street can...

    Persision Performance Shifter

    THinking of changing my shifter in my 727 71 Duster. Currently have a Hurst promatic 2 but adjusting it sucked and the plate on the side with headers makes access tough. I've seen pics of a cheetah scs which is one possibility the other from a cool stand point and some praise I've heard was...

    Best Deep Pan?

    I have a mopar stamped steel deep pan on my 727 which I've never been able to keep from leaking cork gasket or the modern re-useable one for a 518. I've seen B&M Has a cast alluminim version and Milodon has one similar to their oilpans with a billet sealing edge. Anyone have other opinions?

    Price for package deal?

    I'm looking at going to the Keisler 5 speed and am wondering what a fair price for a 727 rebuilt with 2000miles behind a mild street driven small block is worth? It was professionally rebuilt with recipts. Redline racing clutches and kevlar bands as well as a transgo shift kit. It has a...

    Looking at having a new driveshaft built for my car as mine is a patchwork backyard one, It has the smaller u-joints but I have been contemplateing going to the larger u-joints with the u-bolt style pinion yoke as well. On a mild street car is this worth the time? Or should I have my current...

    What Stall?

    Not debating the stall guys I have e-mailed but I seem to be ranging on numbers. The engine shop told me 2800rpm the carb/tun-up guy says 3000rpm -and wants to sell me a B&M- And one of the top converter builders is saying a 10" rated at 3600-3800 Heres the specs, is there something I'm...

    A-518 Pan gasket

    I wanted the new re-useable plastic and neoprene style trans gasket for my 727 and went to get one for an A-518/46RE trans from the dodge dealer. The parts guys had no clue what I wanted so I had to pick a model and said a 92 dakota 5.2. The gasket I got looks like a 904 one aka A-500...

    Slip Yoke has play

    Well after decide not to bother with a new driveshaft and NAPA can't get me a U-Joint unless I measure the cup as 7260 means nothing to them I pulled the shaft out. The slip yoke in the trans seems to have excessive play, it doesn't leak and the tranny was rebuilt. Anyone know what gives...

    Sand in the driveshaft?

    The driveshaft on my 71 Duster 340 727 has been cut down from a 74 fury 4 door -written in grease pencil by a wrecker- by a previous owner. When I've had it off and turn it end to end it sounds like sand or slag rolling through it. It doesn't "seem" to have any vibration issues. Would you...

    Sticking 727

    I rebuilt my 727 this winter, my first trans since I finished the 4th year of my auto apprenticeship. My first torqueflite too. The trans has shifted great UNTILL I made about a 3hr trip with the car and I kept the rpms around 2800 the whole trip. The problem is it makes the 1 -2 shift...

    8 3/4 axles

    My Duster has stock axles redrilled for the big bolt pattern, I've had two different center sections in the car finding the gear ratio I wanted. But one noise follows me a nice howl on the accel side but only at certain speeds. The axles are the culprit I am sure it has the green bearings not...

    Valve Bodies

    I have a transgo shift kit in a good valvebody that was in my old 904. I currently have my 727 apart. I've been told the two valve bodies are the same so the cheap idea is to swap the shift kited valve body into the 27 are they interchangeable?

    Convertors

    Scouting out gettign a new and proper Torque Convertor for my Duster. Dynamic sounds like the best thing since sliced bread but the fact he has no prices on his web site scares me. What brands for a street driven car are worth the cash? and What should a guy stay away from? Also with the...

    Driveshaft

    My Dusters driveshaft formally pulled family duty on a 4 door fury, at least the grease pencil on it says so. Someone had it cut to size and welded, only thing is sounds like its full of sand, assumeign its the welding slag, car gets a nice harmonic vibration at high speed and sure all that...
