Commercial-type sales postings will not be 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!)

We have a Ford V8 engine with 21 stud, that came of a generator. On the deck for the engine number standsIND*18*....Is there a differance between an ind engine and a car engine. Is it the camshaft and why and can I use an ind. cam in a car engine? Thank you.

To my knowledge, there is no difference between the car camshaft and the industrial type. Ford cams are noted for their endurance, and I'd just run it.

Pipo:

I believe that Supereal is correct in that the auto,commercial and industrial engines
all share the same valve timing. You didn't say what year your 21 stud was, but there were some changes made in valve timing (duration) made in the mid-thirties that increased the exhause/intake overlap for increased power at higher rpms. Thanks to improved fuels, allowing for higher compression ratios, the cams were again changed to a "milder" profile in the later 21 stud motors in 37, which made for more low-end "grunt" and improved idle smoothness. The stock 36 cam has a very slight "lope" at idle, owing to its' longer duration. I no longer have the spec's on these, but I still have a NOS 36 cam that could be degree'd if one really needed to know. I believe the lift and lobe separation on all 21-stud cams remained the same, and only the duration changed according to year. This would be a great research project for someone like Lincoln, as hard documentation or even discussion is rare. Back in my dissipated youth, the most sought-after stock camshaft core was a 32, because if was a machined billet steel piece as opposed to all the later cast iron cores, and as such could be welded up to provide more material in the lobe area for long-duration cams
without reducing the diameter of the base-circle. Due to inherent lousy breathing, flatheads
respond particularly well to increased duration. Most aftermarket flathead racing cams are
therefore much more "radical" than their OHV counterparts.

In my spare parts I found two camshafts with other cams than normal one is the press on type the other the bolt on type. Both have the mark 5-T on the front near the ignition slots. They came from different engines. One from a 37 21 stud the other from a 24 stud.
Both were used for a generator plant May be engines from Dagenham U.K.because we live in Europe.

The press-on timing gears were used from 32-40, and the bolt-on type, 35-48. The six cylinder "G" engines used the press-on type, while the "H" type used bolts. The benefit of the bolt type gears was that they could be more easily replaced in the field. Other than the the timing gear attachment, the camshafts were identical. Most press-on cams were replaced with the bolt-on when the engines were rebuilt. Both fiber and aluminum timing gears are used with both methods.
