For sale: Ford D0VE-A 429 CJ Block

You may want to do a little research

You can look it up for yourself. Below is copied not my words:

Please note that while all "A" marked blocks have Boss 429 bulkheads, there are also Boss 429 bulkhead D0VE blocks that don't have the "A" at the front of the block. We have seen them both ways (with and without the "A"). What this means is that if you are scouring a junk yard and find an assembled engine that has a D0VE-A block with the "A" on the raised square pad, you've just found yourself a D0VE-A block with a Boss 429 bulkhead. If the "A" is not there, then it may or may not have the Boss bulkhead (engine disassembly is required to visually verify the existence of the Boss bulkhead features). The "A" is basically a guarantee that the Boss bulkhead feature is there.

The D0VE-A block comes in two primary configurations: 2-bolt mains and 4-bolt mains. The reason for the D0VE-A block's popularity is its thicker main webbing, and also because the main webbing is fully machined from the main caps all the way out to the oil pan rail, which facilitates the conversion of the 2-bolt main blocks to 4-bolt mains. (The standard-webbed passenger car blocks have a section of main webbing between the main caps and oil pan rail that remains as-cast/unmachined.) 4-bolting of the 2-bolt D0VE blocks is usually executed on mains 2, 3, & 4, while mains 1 & 5 remain in their 2-bolt configuration.

There is sometimes talk of D0VE-A blocks that have "Boss 429 bulkheads," and people often ask what that means. In short, it means that when some of the D0VE-A blocks were originally cast, some (but not all) of the casting patterns used for the D0VE-A blocks made use of the front and rear sections of a block pattern originally used for casting the C9AE Boss 429 blocks. The result is that some D0VE blocks were cast with Boss 429 block features front & rear, and some of those specific features of the Boss's block pattern are advantageous on the D0VE-A castings for some applications.

Specifically, the C9AE Boss 429 blocks were 4-bolted from the factory on mains 1, 2, 3, & 4 (not just 2, 3, & 4 like the SCJ blocks). In order to secure a 4-bolt main cap to the number 1 main webbing on the Boss 429 block, it was necessary to add more block material at the outer reaches of the number 1 main web so as to accomodate the outer main bolts (of the number 1 main's 4-bolt main cap) to be added into the block. Another nice feature is that the number 1 main saddle has significantly more material around its perimeter. Together, these two added details of the Boss bulkhead D0VE blocks (the additional main webbing material and additional main saddle material) make 4-bolting the number 1 main of the D0VE block (with Boss bulkheads) more inviting and also improves structural integrity in both the main saddle and 4-bolt main cap securing at the cylinder block.

This should be good....

Albert? Is that you?

What about the post count rule before you can list items for sale?

I have never tried putting 4 bolt caps on one but, I read it somewhere therefore it must be true.

Where is the popcorn eating emoji.....!!!!

Its the reason the rule exists

You guys really need to get a life if this is your big entertainment. I have one 4 bolted on the first 4 caps because I was able to find a boss 429 front main cap for a reasonable price. A 4 bolt main rear cap could be made with a little time and effort.

BTW: if I violated a 25 post rule then have a moderator delete it, certainly not done on purpose and may not have been in effect when I signed up.

Al,

I'm pretty happy with my life, thanks for asking

The "Research" stab is what got you flamed.  Perhaps you should do some research into who you are disputing  

Don't take it personally...  It happens to the best of us.

Could you post pictures of your 4 bolt front capped block? I'd like to see how it was machined.

Thanks

Like to see the 4 bolt on #5 too.

facts

I'd just like to know where the OP copied and pasted that from...

You guys got my curiosity going so I did a quick google search to find some pics of some boss main caps since I have never personally seen any or dealt with a boss at all. One of the first hits I got was a block for sale by Paul way back in July 16, 2011. Advertised as the same thing the op was selling a ford block with 4 4bolt main caps ADDED. And pics to back it up. This is on 460ford.com. Sorry Paul, love you mean it. http://home.earthlink.net/~385series/sitebuildercontent/sitebuilderpictures/bosscapblock_02.jpg

1. If you’re going to quote someone else’s words from the internet, always quote the source/author/link as well because the internet is filled with speculative, incorrect, and erroneous information in every corner.
2. In this case the quote you copied/pasted is indeed 100% correct, but unfortunately for you it does not support your claim (where I quoted you up above). On the contrary, it supports my statement, so you might want to reread what you copied/pasted.
3. By the way, I am the author of your copy/paste and I’d appreciate it if you credit me any time you use my work (or anyone else’s) in an attempt to support a claim such as you attempted in this thread.  

I’ll say it once again here:  there is nothing—absolutely nothing—about a D0VE-A block with Boss 429 bulkheads front & rear that facilitates 4-bolting the #5 main cap any easier than a dime-a-dozen, standard-issue passenger car/light duty 2-bolt block of any engineering revision.  Having the front and rear Boss bulkheads simply doesn’t help with #5 4-bolt main cap fitment and offers no benefit in that regard.

Not that I see any need for 4-bolting #5 in the first place—have you looked at the #5 main on a 385 Series 2-bolt block??? The #5 main cap is clearly the beefiest (ie, strongest) of the 2-bolt block main caps and they most often see the least amount of load of all 5 caps.

Nobody produces a 4-bolt #5 main cap for the passenger car blocks, and if one were manufactured and/or fitted the structural integrity of the outer bolt area of the passenger car cylinder block casting would prove inadequate for providing any benefit.  But don’t worry, BigAl73, because all of this is moot since standard 2-bolt passenger car blocks that were subsequently 4-bolted on 2, 3, & 4 (only) have seen as much as 3000 hp with the OEM cast iron 2-bolt main cap on #5 and lived to tell about it.

I’m not sure why you’re apologizing to me; you haven’t wrongfully contradicted or insulted me in any fashion whatsoever.  Nor does the block in your link support either party’s claim within this discussion.  But...you’ve posted an an interesting side-bar that I think is worth noting nonetheless:

The 4-bolted block that you linked is a D1VE thick-webbed 2-bolt block that has been fitted with 1969 Boss 429 main caps on 1-4.  But look closely at the front of the cylinder block: This is a standard passenger car bulkhead block, not a Boss bulkhead block.



The Boss 429 main cap is fitted properly, but if you look closely at the driver’s-side 3/8” outer bolt you can see that its major thread diameter is peeking through the casting whereas the Boss bulkhead version would offer more material and coverage.  This fitment is nonetheless adequate but if one wanted to use 7/16” outer bolts then the Boss bulkhead is the way to go.

I realize this side-bar has nothing to do with the original matter at hand in this theead, but I thought this specific feature noteworthy of pointing out in the big picture of Boss Bulkhead discussions.  By the way, I love you too (whoever you are, haha).

Whew.....that’ll be $350.

The Boss 429 blocks I've owned were 3/8" for the #1 outboard bolts.
