    Not entirely certain, but I think his '79 is like the '80 pictured there.

    I know the later whales got an upgraded deflector to help guide more air up, I wonder if it could be modified to fit. I donít see why not. I doubt Iíd be able to get one for a box so I might as well try to make another one work.

    They came with the C-4/C5. That is what my 79 ltd S wagon had. Pretty weak especially when put in a wagon and behind a 351 motor. Those transmission could be beefed up to handle the load. Seriously doubt many were.

    Could be worse, the 255 did exist.

    I always thought C4 was the perfect name for that piece of junk given how often they blew up in stock form. They're horribly sloppy things too.

    I never did successfully explain that concept to someone that my confusion at having to grab Second at 5mph in a certain other vehicle wasn't because that car was a stick shift, it was because its First gear was effectively 2.5 times as deep as I was used to at the time!

    Got in touch with Nick yesterday. He's coming down Sunday to do some axle pulling at the junkyard (gonna grab that K-Code axle off that Country Squire), and he's very kindly offered to trailer the '87 back home with him so he can get it to the transmission shop. I guess that's a better plan than trying to drive it up the interstate in 3rd and keep it around 60 MPH. Plus, if something decided to let go further, probably best not to be stuck on some lonely stretch between places.

    Anyway, it'll be going along with a new converter that's rated for a 2200-2500 RPM stall range since the AOD is coming out and I may as well see about giving the HO something a bit better suited to its power band.


    Hopefully 2021 goes better for this car and it won't need any more invasive mechanical work in the near future.

    '87 came home from the shop today. Johnson's took care of getting everything straight, so it shifts good again. Higher stall torque converter is gonna take some getting used to, but behaves fine in local driving, and does still have lockup function in 3rd and 4th, so it won't straight murder my fuel economy. I wasn't really able to do any hard standing starts since the weather was ugly all day, and conditions varied only from damp to raining at intervals. I want to learn the characteristics of the converter on dry surfaces first.

    Swung by Nick's:


    Unfortunately he wasn't home, but had made arrangements for me to pickup a proper tan cargo area carpet he found. Grabbed that, and headed home. TripMinder indicated average economy of 19.6 MPG, so no complaints there. When I got home, I did proceed to clean the cargo mat really well, since I was warned it was covered in dog hair. It's currently drying on the garage floor. Certainly happy to have the car back, now I guess I can start playing with things again, like that radio I've had for a few months. At a minimum, I should get that swapped in, then do the rest of the system at a later date.

    Excellent. Hope all feels well on dry pavement for you.

    Ive been waiting for your radio install. Such a unique piece.

    Drove the car Sunday and Monday, then parked it after it started slow cranking. Took the battery with me to work, and its okay. The alternator, not so much. Bad diodes, recorded over 105mV of ripple and its started whining. Oh well, its been on the car for about four years, it came from the junkyard off a V6 Mustang, and I have no idea how many miles were on it.

    With the time I did drive it, I have found the new torque converter makes the car much nicer to drive. It just feels a more awake, even if you're not hooning it. It can also leave a mean stripe if you floor it now, but it still shifts at 3900 RPM, so still need to do the shift governor. Everything in time.


    Anyway, the alternator... lets get some shiny stuff on!



    But wait, that's not a 3G! I figured if I'm doing this job, we'll go 6G, just because I can. Only thing being re-used is the V8 pulley from the old alternator. This is a brand new alternator from work, designed for the '01-'04 V6 Mustang.



    A little bit of wiggling and it slipped right down into the bracket. Also, this can tilt a lot further than the 3G if you haven't ground down the bracketry any (I haven't), so a factory belt fits fine.



    Looks good here!


    I did run into a brief issue where the amp light wasn't engaging with KOEO. I unplugged it, did some reading, verified by no means was this particular 6G a PCM controlled variant, verified it was grounded, and plugged it back in. The amp light came right on during KOEO.

    Seems to work fine now. If anyone is wondering why I opted for the 6G over the 3G considering it's rated at 110 amps vs the 130 amps 3G can offer, and its the fact the 6G design works a bit better at low speed for improved charging. I swapped from a 3G to a 6G on my '97 with good results, so I figured it wouldn't be a bad idea to do it here.

    Neat. Amazing how new things can just bolt right in all these years later into a car not originally designed for it.

    Good to hear you like the torque converter! Mine just came today lol.

    Ohh cool, was the wiring similar to a 3g? I imagine there are higher output 6gs that could bolt right in. 180+ amps. Might be the new thing to do since 3Gs are getting old

    Which stall rating did you go with? We’re you preferable to the 2500 RPM stall, or something else?

    Wiring is very much the same, just a different connector, and one less wire. Essentially the plug just has the yellow sense wire and green/red lamp wire. Given the install is very similar to the 3G, it wouldn’t be a hard thing to do if someone opted for it. I figure the only folks that would be out of luck are large case folks that had an externally regulated unit, since I don’t think Ford made a 6G that would fit a bracket like that.

    What did you use for the charge wire and fuse? Looks like a nice install.

    Just guessing here. Looks like the factory ford taurus charge wire...Distinct color...been there did that.

    87gtVIC nailed it. I installed it when I first put the 3G on the car before I even officially owned it. I do need to go back and re-loom and clean up the cable routing as it goes. The old loom cracks like crazy and it looks bad.

    Drove the car today and verified with the battery tester output and function. Puts out a good 14.2v fully warm at idle and only showed about 9.3mV of ripple, considerably more acceptable number to the ~103mV when the 3G failed.

    Did you use the Taurus Fuse? If so how did you incorporate it? Direct to solenoid, battery or a fuse holder then solenoid or battery?

    How would a 6g be wired in? Iím thinking of making the switch once my 2g dies.

    One large charge cable with mega fuse

    New voltage regulator plug. One wire to charge post and another to the red/green wire that exists on your current voltage regulator.

    Disconnect old charge cables from everything.

    Yeah, it was the Taurus mega fuse. 175 amp deal, IIRC. I went up to a Vulcan car, and just kinda started yanking and pulled the whole thing right up to the fuse block, then took the mega fuse with the cable. I did the "ugly" install and put a bolt through the cable end and one eyelet of the fuse, then wrapped it in electrical tape. The other fuse eyelet was just jammed onto the solenoid stud.

    Admittedly, I'll probably redo that setup with a proper fuse holder when the Aero fuse block goes in. The cable install was done in that fashion out of convenience and functionality, but not appearance. The only thing I will say that I prefer doing in my charge cable routing that some might argue against is I have always run my cables between the gap of the engine and radiator support, then across the support, and then to the solenoid. When TecNickal and I fitted the Explorer engine in his '89, I tossed a 3G on his car and ran it the same way. I used a Taurus alternator on his, so I chopped down his two regulator wires down a fair bit and trimmed the loom so it looked more appropriate since the regulator comes off the side instead of the top.
