    Upper clutch rod, which way??

    in Drivetrain Tech

    Posted

    The description that you guys gave is hard to put into words.  Trying to describe how to position a crooked stick is tough.   I rigged up the rod without the boot first and swapped the ends until it seemed to stay closest to the middle of the hole.  Then I put the boot on the rod and reinstalled. 

    My 4 speed conversion

    Thanks for the addition Darren. 

    I was able to use my existing crossmember.  I had a TH350 transmission.  I removed the end caps and rubber on the ends and drilled holes to mount mine.  The TH400 crossmember may or may not work.

    I drilled a hole in the steering column plate on mine.

    Please elaborate on the steering column differences.  I assumed that a floor shift would work for either.

    source for speedometer cable for 4 speed

    Hey guys,

    I recently did the 4 speed conversion for my 72 monte. The speedometer cable I got from Ground Up was 80 inches long and had a screw connector on each end.  (I am not sure if it was too long because I didn't take it out of the package).  The cable I took out had a screw connector on the transmission end but  a push lock type connector on the speedometer end.  Ground up says that they have one with the correct ends but it is 100 inches long.  I feel that is going to be too long.   Does anyone have a source for a cable that will work?

    I just wanted to put down a few notes for folks here that are considering a 4 speed swap on their montes.  Last year, I bought a car that I felt would be perfect for a project, just like I wanted.  It was a 72 bench seat, 350 4bbl, th350 transmission car.  I wanted to convert it to a buckets, console, big block, manual transmission.  While it is far from being completed (if there is such a thing), I feel that one of the major steps has been accomplished: the installation of the Muncie 4 speed.  I also have the bucket seats in and have a real good lead on a 454 that could be mine in the next few weeks.  Anyway, I wanted to give a list of parts that I needed for this project, just in case someone wants to take this project on:

     

    transmission

    bolts for transmission to bell housing

    bellhousing

    bolts for bellhousing to engine

    flywheel

    bolts for flywheel to crank

    clutch, pressure plate, throw out bearing, line up tool

    bolts for pressure plate to flywheel

    pilot bushing

    hurst shifter

    (3) bolts to bolt shifter linkage to transmission

    brake and clutch pedal as well as rubber pads for them

    upper clutch push rod

    z bar

    frame mount for z bar (specific for monte carlo)

    frame side z bar pivot ball

    engine side z bar pivot ball

    3 pc z bar plastic bushing with retaining clip

    clutch adjusting rod with swivel

    clutch rod boot

    clutch rod boot retainer

    push rod return spring

    clutch fork boot

    clutch push rod clips

    4 speed hump for console

    clutch return fork

    shifter boot

    console boot retaining ring

    console

    console tunnel

    console trim screws

    console wiring harness

    console extension harness

    console mounting brackets

    flywheel inspection cover and bolts

    starter

    speedometer cable

     

    Here are a few parts that I will need but have not acquired:

    floor shift steering column

    speedometer without PRNDL

    neutral safety switch

    backup light switch

    There may be other things but it is drivable at this point

     

    Here are a few things to consider:

    I am a mechanically inclined person but am not a mechanic.  I spent about a week doing this work, after work and 2 of the days were full days working on the car.  I think I could have done this project in 4 full days.  Now that I have gotten most of it done, I could probably do it again in 3 days. 

    Don't buy flywheel and clutch until you get your bellhousing.  The bellhousing will determine which flywheel and clutch you can use.

    Make sure your frame mount for z bar is for a first generation monte carlo.  All other a bodies used a similar but different bracket.  Our cars need a specific one.  The clutch linkage kit I bought came with everything for a Monte, and I still got the incorrect bracket.

    As far as transmissions go, there are a lot of options with gear ratios, etc.  I would recommend talking to someone that can help you decide what you want.  My car has 2.73 rear end gear.  I opted for a 2.54 first gear in my Muncie.  It operates nicely.  I have good power in all gears.  It probably wont be a tire burner.  I might would go with a 2.90 first gear if I could.

    As far as shifters go, I bought the Muncie but before I installed it, it was recommended that I get a Hurst.  Ground Up offers a Hurst competition plus shifter with a Muncie handle.  This is what I bought to make it look correct.  There are probably other vendors as well.

    When positioning the hump in floor, install bellhousing, mount shifter (not the handle) to transmission and stick it up to see where to start cutting the floor.  You will need to have cross member in as well to get proper position.  I cut a small enough hole for the shifter to not get in the way of existing floor pan.  Then, once the transmission will set in its correct location, I bolted on the shifter handle and placed the hump where it needed to go based on shifter range of motion.  I marked the perimeter of hump, removes it and cut the hole about one inch inside the perimeter of hump.  After welding it in, I used seam sealer to seal the underside and then coated with POR 15 for protection.

     

    I also want to say that I could not have completed this without the great guys on this forum.  I ask any of you to add to this thread to make it informative for any of us considering this swap.

     

     

     

     

    Upper clutch rod, which way??

    Hey there 4 speed experts,

    My Muncie conversion is going very well.  (Thanks to the fine folks on this forum).  I am trying to connect the clutch pedal to the z bar with the upper clutch rod or some call it a clutch firewall rod, depending who sells it.  I just cant figure out which end goes to z bar and which end goes to clutch pedal.  I have tried both ways and not having any luck.  I was trying to copy and paste the part from the Ground Up website but just cant figure out how to do that.  Anyway, it is part number FW 68 on their website ss396.com.

    Many thanks.

    Source for z bar frame mount

    I am converting my 72 to 4 speed and I am in need of frame mount for z bar.  The conversion I bought came with one for a chevelle.  I have ordered one from OPGI and they are saying that it might be 30 days before they get it.  I am looking for one much sooner.  Does anyone know of another source?

     

     

    console mounting braket location

    in Interior Tech

    Posted

    Hey guys, I am planning to start my Muncie conversion here in a week or so.  I plan to install the console while doing this. I am curious about the location of the console mounting bracket.   I feel like I have seen it somewhere before but can't remember where.  Does anyone know where I can find the dimensions for the placement of the bracket?

     

     

    what cfm carb for my 72 402 car?

    in Engine Tech

    Posted

    glad to hear that.  I am also disappointed that my stock air filter assembly will not fit on it.  Mine has the light surface rust that I like plus it would cover up some of this shiny carburetor.  Do you know if there is some kind of spacer/ gasket that would be tall enough to use my stock setup?

    Well, I had good results today, at least with this car.  It seems that my ac compressor and alternator were making some noises from work bearings.  I did end up replacing the carburetor with an Edelbrock.  The only think I have yet to figure out is how to get the AC fast idle solenoid to mount to the carb.  I am guessing that Edelbrock can help with that.  Do you all know of a source for a bracket for this?  Thanks for all of the help.
