Early Ford V-8 Club Forum

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:

  1. All information that you provide to us for your membership is correct.
  2. You will not use your membership to spam, harrass, or exploit other members in any way.
  3. Vulgar, Abusive, Racist and Sexist Language will not be tolerated.
  4. Commercial-type sales postings will not be allowed.
  5. No mass posting or flooding of the boards is allowed.
  6. No Advertising of parts or cars; no Ebay or business/commercial ads (please use the "Classified" for ads Wanted or For Sale).
  7. 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.
  8. 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:

    http://donclink.com/deuce_75_1/images/dscn2950.jpg

    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!)
  9. HOW DO I SHOW MY EMAIL ADDRESS ALONG WITH MY USERNAME? You can LogIn on the Forum, and select PREFERENCES. On this page Members can add optional information such as their City,State, Country; Occupation; Hobbies: list a Homepage; list AOL Instant Messanger Handle; Signature; "Make Email Address viewable to others;" and even change the number of Default Topics shown on a page. WHEN others click on your profile, they will see this information.

I have a customer who wants me to rebuild a '39 V8 engine that has sleeves.
The sleeves are worn quite a bit.
What do I do now?
When I was a kid I think there was an oversized piston set for those engines after the sleeves were removed.

Most shops pull the sleeves and bore to the next nominal diameter. On occasion you will find a block that has areas of thin casting. That's a chance that must be taken and addressed when rebuilding any Ford flatty.
I suggest at minimum a "bell test" be done prior to the expense taken of boring.
Those oversize pistons you recall were (if I recall correctly) .081". They have not been available for as long as I remember.
Another option is to install new sleeves. They are available but costly. Also, you need the proper equipment to install them and dare I say, some experience...

here is my opinion.To give the best service, I would re-sleeve the block to a standard bore using standard sleeves. When you bore it to the next standard size, the engines usually run hot. There is just not enough beef in the block due to the corrosion that has occurred over the years.

Tom, Respectfully I disagree with you about the running hot theory. I have rebuilt more engines than I care to recall. Any and all with sleeves simply had them removed and I'd bored to next nominal size. I have never had an over heating issue. Not once.
However, I have had two blocks that once the sleeves were pulled, turned out to be junk. Now that was disappointing.
I suggested (at minimum) a "bell test" so there could be some confidence that the area surrounding each cylinder bore was in fact thick "enough". This test is obviously free and is quite good at noting thin areas of the casting. Good enough that if an area seems thin to the ear, it would prudently require further testing.

At one time you could just pull the sleeves, hone and install pistons to fit the bore. .083 oversize pistons. Or, you could pull the sleeves and install nos "tin can" sleeves. HOWEVER, those oversize pistons are mighty scarce. I have found nos sleeves but only after months of searching. They are out there somewhere. As Kube says, pull the sleeves and bore to the next diameter. JMO

Pull the sleeves, and run .083 over pistons. The are available from Egge.
The thin sleeves tend to buckle around the exhaust valve area, if the engine runs hot for any reason.

Thanks all.
I called Egge's today, they have .083" oversized pistons in stock.
376 dollars plus another hundred for the rings.
I will have to go that route, which seams like a sure way to get the old turkey running again for a long time.
I will use the original lifters but 8BA valves and guides.

Go with the straight stem valves, the one piece guides are much better, however Ford recommended using the later lifters as the contact area was larger on the mushroom valves. They felt that the smaller contact area of the straight stem valves could lead to cracking of the lifter top.
