Does it really make that much difference whether you have 3.90 or 4.11 CWP ratios? It's only a 5% change.

4:11 means going 50-MPH down the freeway while you flathead straight-8 screams out it's last long song. That 5% means the difference between getting somewhere and getting rear-ended.

I'm just used to Land Rover guys talking about "changing their diffs for better cruising rpm", because when they say it, they mean swapping Series 4.7:1 ratios for coiler 3.54:1 ones. What's the optimum ratio for the Buick, then? Something in the high threes? Actually, my Panda has 5.46:1, which is about the lowest final drive gearing I've ever seen on a factory setup. About 4500rpm at 70mph. Interesting, book top speed (84mph) almost exactly intersects with max power rpm (5500). Talk about wringing out every last drop...

I mean, it depends a lot on the gearing of the transmission, as well as the size of tires he's got on the car. They all affect gear ratios and whatnot. Lots of older cars will have much lower rear end ratios - remember, this is long before overdrive was in every car on the road. I believe my old caddy had 3.06 or 3.10 gearing on it, to give you an idea. 3rd gear on my TH-350 was 1:1, if I'm not mistaken. These Old Buicks tend to have some interesting transmissions, too, so I really don't know if it's a 1 speed, or a 2, and I haven't the slightest idea what the ratios would be. Lobsterboy, I know you'll want to stab me for suggesting it, but if you're dumping money into a diff, just grab something more modern out of a junkyard (camaro or siilar) and get some new leafsprings to match. e: on second thought, a new diff would mean a new driveshaft, and likely modification of the tailshaft on the transmission.

Top gear in a non-overdrive transmission is almost always 1:1, since whether it's an automatic or a manual, it can be achieved by simply locking the input and output shafts together.

Is the 48 before dynaflow? The dynaflow is a 1 speed transmission, which is 1:1 that uses a torque converter to slip its way to accelleration. I think a 48 buick has that, but I am not sure. So its probably fairly important to get the final drive low enough that it can start moving, since there is not really a 1st gear.

'48 was the year the Dynaflow debuted. It was available as an option for the Roadmaster.

Yes, his car is a Dynaflow. It was quite the fancy option that year!

I think a 48 buick has that, but I am not sure. I'm pretty sure Dynaflow was a sort of two-speed. The way I'm thinking of it is that it's a one-plus-low with a torque converter for the high gear. You could start out in low on a hill or whatnot, and then using the normal clutch, change up into high which could usually drive the car around because of the torque converter. Or maybe the gear change didn't use the clutch and you only used it to start off in low? There were several different attempts at simplifying shifting before the automatic as we knew it today took shape. You could stop and start on this without the clutch, low wasn't for everyday use. This is part of the reason for the low rear-end gears in these cars. Lobsterboy could certainly speak at more length on this topic than I could. However I must say I have a particular admiration for the way the Cord shifted gears; you selected the gear you wanted with a small gear selector on the dash, and then stabbed the clutch to execute the gear change automatically. I'm not sure how starting off was accomplished and I'd love to drive one of these old cars with a "semi-automatic" gearbox.

my car is a dynaflow car, and through much deliberation today I decided to keep looking for a taller gear. talked to a few buick guys and as bizzare as it sounds (im putting this together in my head so please correct me if im wrong) the dynaflow never reaches the full 1:1 ratio, so the engineers at buick geared much taller gears to account for its shortcomings. I have a line on a very tall one out of a 55 roadmaster. not quite sure of the numbers but im going to hop on it. so for any of you 41-55 buick guys who dont want that off road gearing anymore... contact me (this has been a joke) Today ms. lobster and I went to Planes Of Fame and Yanks air museum in chino ca. pictures to come...

There is always a bad news that comes with "GOOD NEWS EVERYONE" another wagon trunk picture ![]() thats right, I finally found one, and all the while it was right under my nose. ![]() it checked out, it is in tolerance and it is a good ratio. at 3.36 or shall i say 3.35714286 my less than 1:1 buick dynaflow will be barely turning on the freeway. ![]() the bad news. while driving it over to the shop, i noticed a bit of a different smell, when i parked, a lake of transmission fluid slowly grew under the car. bad bad bad news. looks like we might be doing a trans rebuild as well.

My dad always carried 4 gallons of transmission fluid in the trunk of his buick, the dynaflow always leaked, but was probably a bent pan or something.

cube: scan it!!! if you want, i can scan my 48 trans manual, it might be useful to have for you, Im pretty sure they are very similar with only minor changes from 48 to 58. nice cutty - it looks very clean already! When Fleetwood75 moved here from Detroit, I learned that even some cars from the 80s and 90s are considered classics simply because of the high mortality rate of cars back east. I suppose im somewhat spoiled in the rust department. also, los angeles is pretty much the hub of classic car stuff, just read bringatrailer.com most of their feature cars come from california or other good weather states. here is my friend and club members cutty. ![]() he used to rock 13" hundred spokes, but he got tired of getting pulled over all the time. (this car might be fore sale in the near future...) in other news, my friends at the shop started working on my car without me, ill get some photos tomorrow if i have time/clean hands. i took the rest of the day to work on bicycles - This was my first entry in to the collector bicycle hobby, its a 1938 wards hawthorne, over the last few years ive been non ambitiously collecting parts for it, but today i picked up some of these reproduction brick colored tires, i put the reproduction 30s tear drop pedals and lubed up the original bearings and new departure model D coaster hub and away i went, it rides great with the new rubber. the original "lightning dart" chain tread tires are cool, but rolling around on 73 year old tires can be dangerous and tiring. before: ![]() after: ![]() it was somewhat of a productive day.

Car has new radiator, heater core, intake manifold and valve cover gaskets, plugs/wires/cap/rotor, hoses, belts, thermostat, stainless steel brake lines. I don't have much experience fiddling with carbs and my mechanic is an old school guy who made my old '79 cutlass run great, so I'm leaving that stuff to him. The interior is immaculate, I just need to redo the headliner, since it's sagging all over, rebuild the power window motors (passenger side won't move driver side is slow), and either fix or replace the cluster since the oil, fuel, coolant temp and oil pressure gauges don't work. I'll be making a thread when it eta a bit warmer and the work begins in earnest.

I placed a bid in a silent auction today on a 47 pontiac that has been sitting under a late 1800s home for close to 50 years. the car has 6k original miles on the clock. we will see how that plays out. In other news, this was a very exciting weekend for us - on saturday, we went to visit a family friend in oxnard ca. she knew of our interest in anything old and pointed us to the historic core of old oxnard. this huge neighborhood was filled with 100+ year old homes at less than 100 year old prices. in the next few years, this might be where the lobsterboyx collection would be moving. ![]() ![]() I have more pictures of cool old houses, but this isnt "antique home insanity" on the way back we decided to stop at the camarillo airport to see the air museum - ![]() ![]() ![]() ![]() http://www.cafsocal.com/ we were in for a real treat because they were firing up a spitfire and a p-51 for a photoshoot.

They've done a drat good job on that Delorean, by the looks of things. Very well put together. With the old houses, does the US have an equivalent of the UK's "listed" status, which notes architecture of historical importance, and has different classifications, with differing levels of freedom for rebuilding and departure from the original design? Also, Lobsterboy, if you're ever visiting the UK, see if you can time it to coincide with (and get tickets for) the Goodwood Revival.
