    360 runs strange, lifters??

    I've been trying to figure out a weird issue with the 360 in my D200 pickup for years. Basically what happens is on rapid decel or when free-revving it, when the revs fall it sounds and feels like it's not running on a few cylinders for a few seconds. Does it worse when it's cold. I went...

    WTB brake caliper brackets for 12" rotors?

    I'm in the midst of putting 18" Mustang wheels on my Duster and I figured out I'm going to need to run 1/2" wheel spacers up front to clear the hubs. For that I'm also going to need longer wheel studs so I figured I might as well use the opportunity to upgrade my front rotors from 11" to 12"...

    Speedometer accuracy... can it really be this bad?

    I got this 1972 D200 with a 360 and 727 last November as a non-running project which I've gotten back on the road in the last few weeks. I knew when I put 33" tires on it whatever speedo gear was already in it would be incorrect and I was right; speedo read about 50 when I would be going a tad...

    Diesel engine swaps

    I know this subject has been brought up before but it usually centered around the Cummins 6BT which in my mind is a giant heavy truck engine that doesn't belong in a car (and the 4BT just isn't ballsy enough). I have a few local car buddies who own old-school Mercedes diesels and those things...

    Finally got an old pickup truck!

    And of course it's a Dodge! 1972 D200 Camper Special with a 360-2bbl and 727. Brakes need gone through and it needs a full tune-up badly but for having sat for years it was pretty easy to get started. The last owner to drive it even had the foresight to not put much gas in it in case it had...

    First time road racing at the track!

    After years of wanting to see how my Duster would do on a road course I finally attended a Time Attack series event at Pikes Peak International Raceway. Not to ruffle any feathers but I've had my car down the 1/4 mile several times and there's no comparison, this is WAY more fun! Flooring the...

    My brand new radiator... destroyed.

    Well this happened today. Had to sit around for 2 hours for the tow truck to show up but at least it was free (roadside service through Hagerty). I put a cheap replacement motor mount (biscuit type) on the driver side when I installed this engine and now I'm paying for it! Guess I need to add...

    Chrysler is (finally) bringing out an Inline-6!!

    There’s a Tornado coming: the new inline six Sounds like they're trying to make it short (memories of slant-6 problems?), I wonder how it'll fit in an A-body...

    Light rod knock in a Durango 5.9... is it terminal?

    I'm doing some minor repairs and lots of catch-up maintenance on a coworker's 2000 Durango with a 5.9L Magnum. She made the classic mistake of letting her oil go roughly 8,000 miles since the last change and the engine seems to have (from what I've found on YouTube of similar noises) a very...

    How to Rebuild and Modify A-833 Transmissions by... Jamie Passon!

    Hey everyone, so a few weeks ago I saw a post on Facebook in some Mopar group about this new book that got released which I'm sure you've all been waiting for (I know I was)... Yesterday I went to my local B&N and picked up a copy, it's fantastic! I have an 18-spline box my cousin gave me which...

    Let's see... some awesome in-car videos!

    Hey all, been checking out the forum now and then to keep the "A-body flame" alive while my Duster is out of commission. Another one of my favorite ways to do that is by watching in-car videos of racing or other intense shenanigans in Mopars. Anybody have suggestions? Let's see what ya got...

    Tips for passing emissions in my '88 Chrysler Fifth Avenue

    I know it's not an A-body but it's close and it does have a 318 lol. The problem is the CO readings are too high. It still has the factory "Electronic Spark Control" (quasi-Lean-Burn) computer on it and the Holley 2-bbl with the weird solenoid valve inside. It runs perfectly so for now I just...

    Hood scoop question

    Looked around and couldn't find anything, what are the dimensions (mainly length and width of the mounting area) of the dual-snorkel-style hood scoop like was on the later Dusters, Dart Sports etc? Not the twin scoops like on the earlier models. I'm looking at buying a scoop from AAR...

    Lokar cable setup being a pain!

    Some of you may have seem my thread about the new 750 Street Demon I put on my car a few weeks back. Well since I've owned this car I've been making do with cobbled-together 2-barrel linkage from the 318 I pulled years ago. I decided last week to go the "proper" route and got me a Lokar...

    Tips for starting engine on the ground

    So I'm close to getting my cousin's 440 ready to fire up and break in the new cam. My plan is to set it on the ground and hook it up to the old 727 we pulled out of the same car the 440 came from ('72 Polara). First, if I make sure the transmission is in the Park position, do I still need to...

    Wideband O2 sensor ("shoulda bought this years ago")

    For anyone who has been considering getting one of these but wasn't sure for whatever reason, DO IT. I just got my Innovate LC-2 wideband sensor with digital gauge wired in today and on the first drive with it I found that my Carter AFB has been running no leaner than 13.8:1 at cruise. I...

    You might get a kick out of this

    My cousin needed to transport his 440 short block from his house to the garage we're assembling it at and neither of us has a truck... we both have Jeeps but it's a PITA to "lower" an engine into an SUV. So I got the brilliant idea of unbolting the trunk lid from my Duster and just hauling the...

    Got some new books... must reads!

    Recently "hit up the B&N" and bought a few SA-Design car books. One is for Jeeps and doesn't really apply here but the others are "How to Make Your Muscle Car Handle" by Mark Savitske and "How to Super Tune and Modify Holley Carburetors" by David Vizard. Both of them are brand-new and have...

    Not enough patience for pics...?

    Random rant/vent post so get ready lol :D Anyone else have this problem? Occasionally I like to read through the Members' Restorations section and I have a thread of my car in there which is pretty weak I have to admit... I wish I had added more pics of my car in pieces and parts being...

    How to repair speedometer?

    So my speedometer is jumping around badly... replaced the cable which i know works, no difference. I pulled the gauge itself out and it looks like the part that spins is rubbing the "bell" connected to the pointer; not sure how its supposed to be but the center parts definitely touch. How do i...

    Resto prospect: '69 Polara 2-dr. 383

    Hey guys I'm looking for a second opinion on another Mopar I'm considering buying with the intent of fixing up a bit and reselling for profit. The car in question is a 1969 Dodge Polara 2-door hardtop with a 383 4-bbl and 727, supposedly factory HP engine but I'm not sure about that yet. First...

    First time at the strip!

    I finally got the chance to take my Duster to one of the Test and Tune nights at Bandimere Speedway near me... What a blast! With the engine in my sig I ran a best (out of 2 runs) of 15.3 sec. @ 93 mph. This is with a stock 7 1/4" open rear with 2.76 gears (and BFG street tires), 904 trans...

    Getting sick of gas/blowby fumes...

    I've been putting a lot of street miles on my fresh 360 Magnum in my '70 Duster including a 7-hour (each way) road trip through the mountains. It runs fantastic but the gas and blowby fumes have started to get on my nerves; my clothes often stink of gas after I've been driving for a while...

    Retractable 3-point harness??

    I'm looking for some modern seat belts to put in my '70 Duster and came across these harnesses from Corbeau, they look pretty interesting... Amazon.com: Corbeau 2 Inch Black 3-Point Retractable Bolt-In Harness Belt: Automotive I know it's not recommended to run harnesses without a roll cage...

    Causes of unsteady idle/WTB heater control valve?

    I got two questions here... First, I recently built a 360 Magnum for my '70 Duster which runs GREAT except for a bit of an unsteady idle. I've made sure the initial timing is correct (~10* BTDC) and played around with the idle mixture/speed but it still seems to fluctuate by about 100 RPM and...

    Back-up lights on in forward gears??

    Hey everyone I put a 'new' (running from someone else's car) 904 transmission in my '70 Duster and for some reason the back-up lights come on when the shifter is in both forward and reverse gears. I put a new neutral safety switch in, could that be the problem or is there something else that...

    Modifying front fenders for tire rub..?

    I put a pair of 15 x 7" big-bolt Rallyes on the front of my '70 Duster with 215/65R15 tires and they rub the front edge of the fenders a bit. What's the best way to go about modifying the fender so they'll fit? Can I bend them or is it best to just cut the corner off with a cut-off wheel? Not...

    Speedometer cable issue

    I bought a new speedometer cable for my '70 Duster and it seems like I'm missing something between where it hooks up to the drive pinion on the trans. Anybody have a picture of how it goes? The threaded part of the pinion drive is much bigger than the threaded nut on the end of the speedo...

    Original 318 worth keeping??

    So I finally got my new 360 Magnum in my '70 Duster and I'm wondering what to do with the original 318 I pulled from the car. I was thinking of saving it and someday (at least a few years from now) building it into a turbocharged engine and dropping it back into my Duster. However since my...
