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.

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!)

It is simpler, and less expensive to match the intake with the block. We sometimes mix up years, such as a later cam and "post hole" distributor with an earlier block, etc. Most aftermarket flathead pieces, such as heads, are designed for the 8BA style engines. Much of this is done for cars, such as street rods, where the engine is exposed and appearance is a consideration.

If you have a Ford 8BA or equivalent Merc., I think I'd stay with the later manifold. The later blocks have an internal breather riser pipe in the left front (as viewed from the drivers seat) corner of the valve chest (the cavity in the "vee" under the manifold). This was engineered to vent to the front external breather pipe found on the post 48 manifolds. Switching to a pre-48 manifold presents a rather circuitous path for the crankcase emissions, as they exit the left front corner of the valve chest, and then must travel to the back of the manifold in order to exit through the oil filler, which was really designed as a fresh air intake.

The early blocks had a crankcase vent incorporated in the front corner of the oil pan. If you have a post 48 engine, it does not have this feature. So.....in the interest of good crankcase ventilation, combining an early intake with a late engine can essentially eliminate any exhaust
path for crankcase emissions.

Having said this, If you have a pre-48 block, and want to install a 48 or later manifold, then you have provided TWO paths to get rid of the "bad stuff".

Now-a-days, we think of crankcase emissions as something that we recycle back into the intake manifold to be consumed by the engine. Prior to the advent of the PCV valve, crankcase emissions were something we really wanted to simply "get rid of". Sequestering the contents of these "nasty" emissions within the confines of the engine in any case is not a happy thing, as they contain byproducts of combustion, including acids, and water which do not contribute to a happy environment for our precision "innards".

this would make answering the question just a little easier,
my 3 cents, 37RAGTOPMAN an KEEP ON FORDIN,,,,

The later, 8BA, intake manifold will bolt onto the earlier block, but the oil filler is moved to the front, and the manifold requires the later breather pipe, which also is located at the front of the engine. The fuel pump, stand, and push rod is also changed. There is no provision for a vacuum tap, as the later engines draw the vacuum from a port on the carb.

Are the 1938-48 intake manifolds interchangeable with the 1949-53 V8's if not why???
