    P coded cars are otherwise known as HP cars. Not police.
    I raided a '78 Doba for the current drivetrain in the Magnum. It has a P/S cooler, extra larger tranny cooler, a big A/C condenser. The engine has a upgraded cam, 260/268 duration, windage tray, double roller timing chain and of course, 4bbl. Ha ha ha ha.

    The biggest problem is the way low compresion I measured at 7.8-1. The restrictive exhaust sucked. If it weren't for those two items, the engine may have just performed nice. The rest of the raided drive train went like this;

    The rear is sure grip equiped 9-1/4 with 3.21's. I went and installed 3.55's.
    I added a deep MP trans pan. No other mods.

    The engine;
    The engine got a MSD and MP distributor. Headers with 2-1/2 inch pipe and a "H" pipe connecting the 2 sides. Mufflers are Hooker Aero Chambers.
    I just swaped on a Holley Street Dominator intake. I have to fiddle with the T-Q before I put it back on. Hard to start the cr with that carb for some reason. Even on the stock intake. So a 750 AFB sits on top for now. The T-Q did work well with the Holley intake. (When it was warm outside.) The AFB feels a little muddy.

    What codes do you look out for when looking for a car like that?. I would have thought that a Cordoba would have less heavy duty stuff and more luxury stuff than a Magnum or Charger so I guess you were lucky to find your parts car.

    I don't look for codes, I just eyeball what it has and make a move to get it or leave it. When I looked at the parts Doba, the seller wanted $800 and wasn't moving on the price. He did not care if it sat. I tried to bargin with him on it for a couple of months and decided to wait. 8 months later, it was still there and he didn't care if it sat longer, he wanted $800 and that was that.

    So I paid.

    The "P" code is in the vin.

    rumblefish360, you must have lots of space to be parting out and tearing down cars all the time. Got a big garage and accomodating neighbours? Got any shots of the cars you have been parting out. Where do you store all the parts?

    As usual, lotsa questions!

    rumblefish360, do you know much about the steel sunroofs that were available on Cordobas and Magnums. They seem to be a rare option, although I have no idea of the production numbers. Do you know if there are all manual wind, not power. Know anything about them? They may have been available on the Furys and Monacos also.

    my dad was a chrysler tech from 1968 till 1985 when he opened his own repair shop. he frequently drove dealership customer cars home to duplicate drivability issues, as it was a pretty long trip. although my love is late 60's and early 70's cars, i have fond memories of the old man working on magnums, cordobas, gran furys and volares in the driveway at night in the early eighties. one black roadrunner with orange graphics was the victim of his right foot one night, and i remember in particular one guys injected imperial that he had to work on because nobody else at the shop would touch it!

    I have a 2 car garage, that's it. The driveway can hold 4 full size cars. To the left of the garage, the grass can hold another 4 easy, if they were Dusters instead, maybe 6 cars. On the otherside of the house, I have a second driveway. (Don't ask, that's the way the house came.) It can hold 3 more cars. Then, I have just shy a 20 car holding area in land that dosen't effect house parties or the swimingpool or swing set area.

    I have nobody next to me on the left and really nice people on the right that could double as ghosts. Accross the street doesn't give a rats butt on anything and that everybody within 500 feet of me. I could lay 100 ft. strechs of rubber and no one comes to the door no matter what time of night.
    (The old lady across the street didn't know I own a Harley with straight pipes until she drove by after 3 years of riding it and going to work at midnight at WOT!)

    I don't part cars out. Just get what I need and junk the rest.

    In the garage, back porch, basement, back shed, side of the garage and under the bed. (No lie)

    You mean the steel roofs that roll back into the rest of the roof? Moon roofs? No. I've only seen pictures. I don't even know if there crank or electric.

    Mr.B;

    I heard those F.I. set ups were nightmares and the techs were untrained on them back in the day. I know a few older fellas that had them, had trouble with them, slammmmmed dunk a carb on top and it was fine, passed the test just fine and live very happy after that. Once in awhile I pass one with the OE , F.I. set up running like it should without issue. Rare that is.

    I'm about feel over 95% sure you have a Magumn GT. The sliver dash and console trim more or less tells the tale. For some crazy reason most Magumn GT's did NOT have GT in the wheel centers although they were supposed to. It should have GT on the panel above the glove box. But who knows Chry. just didn't get it right in 78 and 79 at all. Many of the Magumns we got in had Cordoba rear seats and a Chrysler emblem in the Steering wheel. Most GT's we got had the wood grain dash treatment also which was wrong.
    The way to verfiy its a GT is the data plate will have a trim code of A-75 for the GT.
    At any rate you have the makings of a very nice car, most had vinyl tops, and I think the cars look much better without the vinyl top.

    Thanks for the comploment, but I DO NOT HAVE A GT! It is a XE car with dealer dressed up GT stripes, that have been painted over after it was hit and repaired.

    The turn style dash and center console plate were added by myself.

    GT's could be had with and without all the items you have listed. GT's came with and without Road wheels, fenderflares, buckets etc.......

    :rolling:You have no clue! All 78-79 Magnums were XE's, The
    The A75/GT is a suspension package!
    GT package came with:
    -GT Suspension
    -Two Silver GT emblems on either side of the car replacing the
    black XE's. There were no other places the said GT on these
    cars! All the other places still have XE's due to them all being XE's
    -Silver machined swirled dash that did not include a tach.
    The tachometers were an extra option. 78's got 100mph speedo's and the 79's got 85mph speedo's
    -They came with 3 peice GT style steel slot wheels w/rings & centers.
    -Wheel lip-fender flares (These could be deleted)

    The GT package had nothing to do with the Engine, Transmission
    or the Rear end! And, No they did not have GT in the wheel center caps.
    It's very popular to take the wheels, flares and the dashes out of
    wrecked GT's and place them in/on to XE's.

    Magnum's came with multple options on the interiors, read up.

    I not sure where you worked but, your bosses ordered the weird options. Probability
    that they were confused on how to order correctly. I was easy to delete options
    if you wrote the wrong thing back then.

    I know what I'm talking about as I own many Magnums and have for
    many years from the 70's!:tongueflap:LOL

    Thanks Rumblefish, You know for what!
