Cory do you really want to get added mileage and improve the life of
you engine. I read all the articles here . I suggest a test on the dyno to set a base line and make any adjustments from there . you can always go back to the dyno and see if your still holding true . I did with this new product called CCF from American CCF and it showed a 10 -15% increase torque and HP at 4000 ft. checkit out at americanccf.com |

Unless you really feel the need for the OD, I'd keep the FMX. AFAIK it's closely related to the old Ford-O-Matic and therefore the Borg-Warner automatic that Studebaker used from 56-64, and that tranny is one of the most underrated units out there - very durable, reliable, and basically abusable. I know a guy that was pumping over 600 RWHP through a Powershift (basically a fancied up HD Flightomatic) and ditched it for a THM400 because everyone told him it would be stronger... and promptly blew the THM400... I'm really not sure what the reliability of a good AOD is, but I seriously doubt it's as cast-iron, dead-nuts reliable as the FMX/Ford-O-Matic/Flightomatic. Of course, if you have a 9" rear, it's trivially easy to play with the rear gear ratio, and I can see the appeal of having a tranny with a wider gear spread. So if that's what you really want, and this car you think is a keeper, by all means go for it.

I'm really not sure what > the reliability of a good AOD is, but I seriously doubt it's as > cast-iron, dead-nuts reliable as the FMX/Ford-O-Matic/Flightomatic. The FMX can definitely take more abuse than the AOD (and yes, it is very similar to the old Borg-Warner, was based on that design). Also not fancy TV linkage to worry about getting out of adjustement and burning up the overdrive band. The FMX is a heavy trans that robs a lot of power though. I've got a heavy car with a small engine, so a lighter more efficient transmission may do me better. I think the old FMX still has a good 50k-100k left in her though. Shifts very nicely when it above freezing or it gets warmed up. I just figgure if I'm gonna be shelling out for a new tranny I may as well get one that will help with mileage since this car is gonna be my daily driver for a long, long time. > Of course, if you have a 9" rear, it's trivially easy to play with the > rear gear ratio, and I can see the appeal of having a tranny with a > wider gear spread. So if that's what you really want, and this car you > think is a keeper, by all means go for it. I guess I just felt > compelled to stand up and defend the honor of the FMX there for a second Unfortunately I don't ahve a 9" out back... Many small block cars came with a smaller rear which got the job done fine. As I understand it there aren't really any option for gearing for this rear end. I know of a couple '67 and '68 Gals in a pick'n'pull yard not far from here. At least two have 390s so I figgure I have a good chance of finding a 9" that'll just bolt right in. Maybe I'll get lucky and find one with a decent gear ratio. Then I can just clean it up, put new bearings in, and be all set to go. I actually pulled a gas tank a year or two ago from a '67 with a 390... Didn't pay much attention to the rear end but IIRC it was a 9". Anyhow, the FMX certainly is a good reliable transmission. The one in my '67 went to 200k before it started slipping on the 2-3 shift when cold out. > > As for the brakes, I generally don't drive faster than 80-85 as that's about > > the upper limit of what my car can do in a full-out emergency stop and not > > have the brakes overheat as I approach a stop.

I like the ones where I don't have to replace the spindles or any of the steering linkage. Just bolt it on and be done with it. Thanks for the input on the brakes, definitely something to consider when the time comes to do the swap. |

Yeah, that's what I was thinking... This was my great grandma's car. The Galaxie is a family car, and a 2 ton car with a small engine and tall 'highway' gears isn't exactly a sporty muscle car. The vinyl top (which I think looks sharp) probably doesn't help the 'sporty' idea much either. If it was a fastback it'd be sporty looking. My old '67 Galaxie hardtop (hardtops only came in a faskback style) was pretty sporty lookin', but certainly wasn't the quickest thing around with a little 289 and 2.80:1 gears. Both my '67 and '68 were made for mileage with the small engines and tall gears. The highest I ever saw was a hair over 17 MPG with the '68 using a 2 barrel carb. The '67 got slightly less than that at most. |

Approximately the same temp, wasn't very windy in either direction, everything was pretty much the same. > -On the same stretch of road (hilly?) Yep, same roads each way, both directions run next to eachother the whole way. > -What about wind? Not much wind going either direction > -How did you calculate MPG? (Car computers are not THAT accurate IME). Computers? We're talkin' about a '68 Galaxie here. I filled the tnak and did the math... No topping it off or anything either way. > -Same type of gas? Ran 93 octane both directions. Bought Sunoco in NJ and Shell in CT. Both are good quality gas so I doubt there is much difference in fuel quality. > -Same vehicle weight? I had a few extra things on the way back, not more than a 20-25 lb increase though. Even if you figgure a couple tenths of a MPG error from various things, such as perhaps the pumps at the gas stations shutting off at different levels giving slgihtly more or less gas at one station, it still isn't a significant change in mileage for the time saved (over half an hour). I will say though that driving at the higher speed took more attention and left me feeling a little more drained when I got home. Perhaps most of that was from not sleeping much while I was in CT though. |

I did with > this new product called CCF from American CCF and it showed a 10 -15% > increase torque and HP at 4000 ft. checkit out at americanccf.com I have never put any additives in my oil. The oil manufacturer puts in the required additives. More is usually overkill and typically hurts the effectiveness of the oil. I also don't like the idea of putting ceramics (solids/particulates) in my engine. Solids in an engine can't be good for it, not to mention that a good oil filter (I use only Purolator PureOne) should filter most, if not all, of that stuff before it gets to the bearings or has much chance to get on the cylinder walls. My engine only has ~16,000 miles on it. If it needs a freshening up I'll pull it out, put new bearings in, hone the cylinder and re-ring it. Cheap and effective. I may do just that come spring when I pull the engine to put new performance heads on, a Weiland Stealth intake, and change my oil pan gasket, timing cover gasket, and water pump (got a new aluminum pump laying around I may as well use). I figgure while I've got the engine out it'll be cheap insurance. I think a day on the dyno is a bit much for a mild daily driver. I'm fine with doing my tuning with trial and error on the road, reading plugs, etc. May not squeeze as much out of it as on the dyno, but it's good enough for what the car's purpose is. Now if I had a built up motor a good tune on the dyno would be worth it. For a mild 302 in ym daily driver... Nah, it's not worth the extra cost (to me anyway). Cory |

Sorry, I wasn't alive back then but the car does seem like a muscle car
to me. I saw two doors on the car when I did a websearch. A coupe tends to be more sporty looking. If you don't want to call it an American sportscar/musclecar, you can't deny it's a big, heavy car with a typical American build for the time period - heavy, big inefficient engine, sucks lots of gas. Of course driving it fast won't make that much difference in mileage. Now lets compare a modern car. Speed will make a difference in mileage there. |
