FORUM RULES: Users agree to these Rules when using Forum.

The site administrator reserves the right to change the terms and conditions of the user agreement without prior notice to the user. It is the responsibility of the user to regularly review the terms of this agreement.

The user agrees to the following terms:

All information that you provide to us for your membership is correct.
You will not use your membership to spam, harrass, or exploit other members in any way.
Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
Commercial-type sales postings will not be allowed.
No mass posting or flooding of the boards is allowed.
No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
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!)

for 1941 the block is different than the 81A . The 81A was used from 38 to 40 it has a flat surface under the intake manifold. The 41 block has a raised surface under the intake manifold. The 81A block is shown below.

41fatty, yes, they are out there, but if your present block is re-buildable, you might just do what I did with my 59L engine in my '38 Ford: Concentrate on ensuring that the bolt-ons are correct for the year, and almost nobody will know the difference. You'll end up with a correct-to-the-eye engine that benefits from a few subtle improvements over the 81A block.

You have a postwar series 59 block. These blocks were introduced in 1945, and continued through 1948. They remain today as the most popular of the Ford flatheads.

I have a 1937 4dr humpback Ford. It has the larger engine, but is not original. I believe that it received a short block repair sometime after the War. I think that it has most of the '37 engine accessories. I'm thinking of having the engine rebuilt this summer and would like to ID what I actually have.
First it has 24 stud heads with the water inlet in the middle of the head. I've seen a 59 cast in the bell housing. It has a Stromberg 97 carburetor. What else should I be looking at? Thanks, Mike.
