Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.

VIEWING MULTIPLE TOPICS ON SCREEN: You can choose to see more than 10 Topics at a time ... Log In and choose "Preferences" from the top bar on the Forum page. Scroll down and Change the "Default Topics Returned" parameter to 25 or 50, and save the changes. Since this setting is stored in your browser 'cookies' (if enabled), it seems to use that stored value even if you are not logged in. So, if you use a PC that you haven't logged into the forum from, the setting still seem to remain at the default.
EXTERNAL PHOTO LINKS ON FORUM: You can still use external photo links in your posts on the new forum. They follow the rules of any link in that they have to have the URL link qualified down to the full image file name (example: .jpg). The links will open in a new browser window, the same as an uploaded image attached to a post. Since an image attachment to any post does not display inline with the post, the results are the same. You can use multiple external links within a post. This link is from photos on a site from Don Clink's 'Deuce@75' albums:

Using links from photo sites such as Photobucket can help in "size" issue with uploaded attachment files. For best viewing in web browsers, photos should be around the 800x600 pixel range, and probably not more than 1024x768. Most cameras today store HUGE jpg image files, as the default settings are in the 7, 8, 10, and 12Mb image sizes. The image files that are then attached are very large, and the browser can't display the full image size without using the scroll bars. Use the re-sizing functions of your photo editing software to reduce the image to 800x600, which reduces the file sixe and the image load time in the browser. Don uses Google's free Picassa3 software, which is an excellent photo management product. All of the photo albums of the Deuce, Grand National, and Auburn that are links on the NORG site were built using Picassa's web creation functions. And it's free? (THANKS to Don Clink for the info!)

Hi. I am working on a 1940 Ford Standard Coupe V8 60hp all stock. Im looking to upgrade the stock 4.44 rear differential to a 4.11 or another ratio if possible. Has anyone done this while keeping the original motor? Also if possible would it make a noticeable improvement and worth doing? Any advice would be greatly appreciated. Thanks
Ron

My guess is that a 4.11 would result in a little less pickup and a quieter engine at speeds above 40mph.

Ron - agree with Tom and add that another consideration is the speed, type of terrain and corresponding rpm you typically cruise at. A reasonable assumption is the 60 hp motor realizes optimum torque at an engineered/designed cruising speed for the time (likely 45 mph). If you change the rear to a 4.11 the optimum torque rpm (whatever that may be for a 60 hp motor - it is ~2,500 rpm for my '47 100 hp) will be realized at a higher speed for which air flow and wind restriction may exceed the 60 hp motor's power ability to comfortably and efficiently (i.e., without over-heating) maintain that speed, particularly over rolling terrain. Not to mention the suspension of the car was likely engineered to dovetail with these design/speed considerations as well. Something I'd give some thought to before making the change (typical cruising speed, type of terrain - slightly hilly, mostly flat, or mountainous - you typically drive on, optimum torque rpm, etc.).

Perhaps kubes40 has some hands-on experience here as well that will help you make this determination.

Okay, I guess I was kind of, sort of, asked for my .02¢ so here it is:
LEAVE the 4:44 in place. I have had a few 60HP cars and even with the 4:44 they can barely get out of their own way when attempting to climb an aggressive grade.
There's a reason ol' Henry but that stiff gear in there - it's necessary!
Bottom line in my humble opinion? Leave it as it is. You will be sorely disappointed if you go to even a 4:11. A 3:78? Forget going up any hill... ain't gonna happen.
Respectfully, Mike "Kube" Kubarth
