  1. TRANSMISSION TALK- 700 R 4,//200 4R,//FMX

    in 1963-64 Avanti

    Posted

     Thanks Bob:  A trans shop indicated the Bell Housing on the FMX was huge and would require a lot of fab

    On the FMX what do you use for a shifter.  Do you need a different starter and a cable for the Carb?

    They were not fans of the 200r4..Wondering what others feel.

    From another post I see the 700 R4 requires a lot of fab  If I get ready to do this could I get your contact phone NumbeR

    We just rebuilt our torque converter and increase the stall speed.  I have a brand new engine and I have some performance tweaks I can do

    If this does not increase performance, I will consdider the swap.  I have a 331 rear end

    I am told you should go to 373 for the 700 R4

    what did you use for your FMX

    Who out there has swapped their original transmission for any of the following:

    1. 700 R4

    2. 200 4R

    3. FORD FMX

    Can you share your build experience regarding: Any info regarding problems, costs ultimate results is greatly appreciated

    1. WHAT IS THE BEST FIT

    2. WHAT BRACKETRY DID YOU HAVE TO MAKE OR PURCHASE AND FROM WHERE

    3. WHAT DID YOU DO WITH YOUR REAR END

    4. WHAT DID YOU DO WITH YOUR DRIVE SHAFT

    5. WHERE DID YOU SOURCE YOUR TRANSMISSION OR DID YOU FIND A CORE AND HAVE IT REBUILT

    6. RECOMMENDED VENDORS FOR NEEDED PARTS

  5. PERFORMANCE OFF THE LINE R1

    spelling

    GLENW  poor performance in D and in 1st...Stock torque converter stall speed should be 2100... rpm

    I tested stall speed by holding brake and accelerating to stall and it was about 1200 rpm

    Clearly something wrong with this torque converter.. It is either worn out or is the wrong converter

  10. POOR PERFROMANCE OFF THE LINE FOLLOW UP

    The stock Avanti Torque converter has a stall speed of about 2100 RPM

    The code on the converter is HR with numbers following

    As it turns out, my converter is HH meaning that the transmission was probably worked on at 

    some time and a different torque converter was used.  I checked the stall speed by putting foot on 

    brake and revving engine until it stalled and I got to no more than 1200 rpm.. so I have no

    low end torque and it does not appear to be a matter of timing or carburetion.  ( carburetor was 

    rebuilt by an exoert no more than a week ago) I believe  I sourced an HR converter which can be rebuilt

    The trick will be to pull the transmission without pulling the engine.. Can be done by those who have the experience

  12. PERFORMANCE OFF THE LINE R1

    Studegary.. this is how it performed even with my old engine..

    I had a picture of the torque convertor when it was oput and you could see the stamping on it.  I sent that to Jim Pepper.. Granted it was not the best photo and you had to magnify it.  Here is what he said

    According to the shop manual for both the Avanti or regular passenger cars, none of the production converters have your marking. The Avanti had an “S” stamped in it and was painted with red primer. Avanti powered Larks and Hawks got no stamping and were painted black. These torque converters had a stall speed of 2100 RPM minimum. The standard production converters had FT stamped in them and had a stall speed of 1750 – 1850 RPM behind a 289. I am guessing that your trans was rebuilt at some time in its life and a stock type replacement torque converter was used. This would explain the sluggish performance.

     

    So:  NEW ENGINE, COMPLETELY REBUILT CARBURETOR, TIMED AT 10 DEGREES BEFORE TDC, TESTED WITH VACCUUM AND AGAINST THE CURVE OF THE DISTRIBUTOR, WHICH IS DAVE THIEBUALT'S MOPAR DISTRIBUTOR AND  THE PERFORMANCE TAKE OFF FROM DEAD STOP IN FIRST GEAR IS  THE SAME.  YOU DO NOT GET ANY POWER IN 

    1ST GEAR UNTIL ABOUT 1500 RPM

    I know I am the third owner because I know the person I bought if from very well and he purchased the car from a long term friend.  I have some original paper work back to 1992 at which time the car had 51,000 miles and it now has 74,000 miles.

  14. AUTOMATIC TRANSMISSION CONVERSION

    in 1963-64 Avanti

    Posted · Edited by studequest
    error in original post

    Has anyone converted the R1 Automatic Transmission to a 700 R4

    What parts are needed, who are best suppliers for those parts and if you farmed it out, what could one expect for labor?

    I know a trans from summit is about 1700- $2000

    Thanks Keith

  17. SPEEDOMETER DEAD

    in 1963-64 Avanti

    Posted

    A few years ago I replaced the pinion gear in the rear end.  Car has been idle for 4 months while engine was rebuilt

    I noted the speedo was a little skiddish,, but it was accurate based on Freeway speed signs.

    THEN .,... NOTHING.... likely causes>  This is an R1 with automatic.

    Thanks Keith

  20. Fuel tank capacity and fill-up

    in 1963-64 Avanti

    NIFTY IDEA GUNSLINGER

    Well.,  I put in a new sending unit and clearly it is not correct because it is not moving past 1/4 tank and as I ran out of gas today that is clearly not

    Normal so my new empty will be at 1/4.. When I filled up I had 18.6 gallons and it was not all the way full so I believe it must be a 20 gallon tank

    I plan to go off mileage at 12 ,pg so a total of about 210 miles between fill ups PLUS a 2 gallon gas can in the trunk!!!

    Avanti Brethren:

    i am looking for thoughts on this.

    Does anyone think this could be a carburetor issue even though it was rebuilt

    Would anyone change this to an Eddlebrock and if so ... which one?

    I  have a 63 R1 automatic.  The engine has been completely rebuilt

    It has the original trans and rear end: I am a bit disappointed that my take off in first gear is about what I had before I rebuilt the When you start in first the car lugs until about 1500 to 1700 RPM until it will get some power

    Here are the stats
    The current idle is 500.. BOB Halgren made an adjustment but it seems to be at 500
    The timing is 10 degrees
    The op temperature is about 170
    The oil pressure is 60
    The original carter carburetor was completely rebuilt with its accelerator pump and check valve
    There is no dieseling and no pre-ignition

    FROM JIM PEPPER:
    I am only guessing but I'll bet the advance curve is slow. This is the
    advance versus RPM curve. Study the graph and you will see that it starts at
    about 700 - 800 engine RPM and goes up from there. When you had the engine
    out did you look for the proper ID code on the torque converter? (I DID NOT CHECK THIS) A stock
    converter will give sluggish off idle acceleration as I mentioned several
    months ago.

  24. FUEL INJECTION FOR 1963 AND 200 R4 TRANSMISSION SET UP

    in 1963-64 Avanti

    Posted

    You bring up very good points  Here is the path I am going on right now.. I would like to keep the car as close to what it came with.  I have to rebuild the engine

    Tell me more about the Positraction

    this car has always smoked even though performance has been good, but I am getting piston slap and I am smoking too much now

    I checked the variety of fuel  systems I was thinking of; HOLLEY SNIPER, EFI AND EDELBROCK

    While these appear to be straight forward the parts and labor probably approaches $3000

    I suspect I am into engine for $4500

    Transmission could be another $2500  soooooooo

    1. I am keeping my standard carburetor for now

    2. I am changing the rear end to 3.73 gears

    3. I will then test the car to see what I have..

     

    Thanks for the response.... Keith
