And what has to be done to use the 350 diesal block?

Can I just take the long blcok and put on the heads and manifold and go. I know that the head bolts need to be 9/16" or drill out the older heads to 9/16" bolts holes. I would also be putting in the Edelbrock 7112 cam to match my current manifold

Can it be done and has anybody done it?

Unless you are looking to make big power with a power adder why bother. Just build an early 350 block.

Check this website out. It has some pretty good info on the diesel engines and what is involved into making it run on gas.

Redog

^^ I did already

I just wanted to know if anybody has done it.

I have an early 350 block, I was just looking for a different or cheaper route since Mondello has a new 350 DX block for $1500.

quick86silver

Theres some info on DX Blocks on 78-88olds.com but it doesn't look like anyone has actually done the buildup. Theres a good Mondello article and a few other links.

Am I missing something? Why would you pay 1500.00 for a block to save $$ The 350 you have is free. Starting with a new block does not mean it won't need machine work.

Again the only reason to build a DX is to hold to extreme power. A build under 500HP I would not even think about it.

Also you are looking at a min 300.00 to ship a block if not more.

Redog

^^ Yeah I guess so.

I was just thinking of everything.

This won't be happening for 2 years anyway

OK, I got to ask where you're going with this? To start by buying a $1500 bare block then having to find a DX crank isn't going to be cheaper. And with the larger main journals engine RPM is going to be reduced compared to a standard 350. A 350 doesn't have the CI/torque to make up for the lose of RPM's as compared to a big block. And I don't think you are planning an exotic build if you're asking the "cheap" question.

So I'm guessing what you are really asking: 'Is starting a 350 build with a 350DX block a good idea?' My opinion, No! Build a standard 350 and it will be cheaper, rev higher & you'll be happier. If you want the best bang (no pun intended) for your bucks, build a 455. If you want the best mild performance small block consider using your 350 crank in a 403.

Just my opinion, Don

Oops! I spent too much time talking about blackberry cobbler.... gearheads78 said about the say thing, with a whole lot less words.

If you want a DX, buy one from Dick Miller.
Cheap is negated however if you do.

If you have a DX block build it as a Diesel engine and put it in a 1984 Custom Cruiser. Then you can put farm diesel in it and save a bundle on fuel costs. The cops will never think to check your old station wagon for the red dye.

You HAVE to move a head locator pin also. Not easy, you have to use the head gasket to locate and drill the hole for the locator pin. Make it straight.
$1500 is WAAAAY too much for one of these things, unless new. I had one of these for sale locally for $300.
I built one years ago, and ran it until I spun a bearing. FUN. The reason they do not like to rev is because of the heavy assed pistons and rods.
The best scenario for this build is to get some #8 heads for it, put in some bigger valves, and hit it with a 350 shot of nitrous between 3500-5500 rpm.

It's NOS, and it's been for sale for a loooong time.

I got my DX for free. Didn't take the D block that was offered with it. Didn't know any better at the time.

Original plan was 4.125" x 4" combo. Wasn't happy with the available rod angle choices, so it's on the shelf. If/when I do screw it together, I'll probably go to 4.25" and use a 350 crank.

Norm you feeling OK buddy? I noticed no sarcasm in that post

I have the same block will sell for 500.00 350DX .842 lifters new

88 coupe

A DX with .842" lifter bores?

Norm

raadon

yup, the one mondello has should be small lifter too, or it is just a regular production block.

88 coupe

From here, they look like 921".

Its a GM diesel short block. He probably snagged a some of the last that came off the line. If so, it would have .921" lifter bores.

What did you think it would be?

Norm

raadon

Looks like .842 lifters to me. They made a few of them. Greg Godon got a few of them from Warren Johnson a couple of years ago. A couple others on ROP had them. I bought this one I have in '95 for $250...so I'd sell it for $500.

88 coupe

No answer?

"DX" castings ('81 and newer) used .921" roller lifters, as opposed to the "D" castings ('80 and earlier) that used .842" flat tappets.

Is yours an exception?

Art Rizzi will be using one of the same, in his Super Pro. Russel Hunt and Bill Trovato have been using them for several years.

However: Those are Batten/Nascar blocks, not to be confused with, "D" and "DX" which are a different casting.

No doubt.

Norm

raadon

Pretty sure Art has a DX with 2.5" mains with .842 lifters. And thick straight oil pan rail. Somebody had one on the other day that was a diesel "D" block that had .921 lifters. As far as what block I thought Mondello's had would be the same one I have. That is probably the only thing that distinguishes it would be the small lifters. It still has 3" mains. I will sell it because I' think I'm going to buy that 4 bolt aluminum block. (They probably say they never made that either). Bottom line they made many different versions of DX, D, and nascar blocks.

raadon

Obviously you have no clue how much it costs to bush the lifter bores if you want to run rollers. That alone makes the block a steal.

captjim

" However: Those are Batten/Nascar blocks, not to be confused with, "D" and "DX" which are a different casting."

Incorrect, unless Art is mistaken.
If this is the engine that is being referenced, here are the specs,

That from Arts website. It is a DX block with .842 roller lifters, however it does not say whether they were bushed.

Russels is a Nascar block, here are his specs,

^^^^^^ I think that pretty much sums up Norm. Put it this way Bullwinkle, I have a DX block with .842 lifters, and can prove it...how much money do have to wager on it??? You aren't as smart as you think you are.

88 coupe

Obviously.

I specifically chose the "DX" so I could use .921" lifters.

"DX" came with rollers, no machining needed.

If I wanted to use .842" lifters, I would have picked the "D" block. The cost of the unnecessary machine work would probably buy a lot of beer

Yes, it does.

If I was selling a "bushed DX" block, I would describe it accurately in my opening post, in order to justify the price.

Norm

raadon

That's because it isn't bushed...are you that dense? Like I said how much money you got, you seem to think you know everything? Show everybody on the board how much of a bigshot know it all you are and put some money on it...I got $5000 cash says I not only have one but there are many more...Come on Norm...put your money where your mouth is.

88 coupe

Having a little trouble keeping up with a simple technical discussion, are we?

Did anyone say anything different?

This reaction, looks like a textbook example of a BS artist who has been backed into a corner.

Actually, I already know that.

Norm

raadon

Wanting to prove you wrong and I'm the one backed into a corner...I can lower the amount so you can afford it. I'm sorry you are clueless...call Art and he will set you straight. His block is a DX with 2.5" mains (no spacers) and .842 lifter bores "no bushings" you can stick your head in the sand if you want but you're wrong...admit it and be a man.

88 coupe

Not dense. Simply stepped into your trap. It will not happen again.

The more there are, the easier it will be for you to document their existence.

An inquiry to Chris Witt (Octania on ROP) would be a good place to start.

BS artists are obsessed with "proving" who is right, and who is wrong. It is an "ego" thing that is counter productive.

If you have "proof", show it.

Yes, you are.

Your insults/name calling/flames, are not "proof" of anything. To the contrary, they are the favored tools of a cornered BS artist.

The kind of childish BS that belongs on a "ricer forum".

So am I. I will be less so, when you show your documentation.

Not the way it works. You are the one going against common knowledge, the burden of "proof" is on you.

So far, the only support you have, are your own unsubstantiated statements.

What you, and the other trolls do not realize, is that there are more than a few CO members, who will correct my technical errors, in a heartbeat. Did you notice how quick captjim stepped up?

You can "wager" whatever amount you would like, that if I made a technical error, anywhere in this thread, everyone would have known about it, in short order.

You can donate your loss, to your favorite charity.

I make it a practice to acknowledge my mistakes as soon as I am aware of them.

If/when you have anything of substance, post it. If you do not have anything, you can continue your pizzing contest by yourself.

Norm

raadon

Bullwinkle, I am willing to wager money because you are calling me a liar...you're the one who started with the smart assed comments and name calling. There has to be somebody on this forum in the Lansing, MI. They are more than welcome to bring a .842 lifter and fit it to this unbushed block and make an *** out of you. Maybe I should link this to ROP and let them vultures come down and pick you to pieces. You are a complete tool.

When Greg said 1st gen. hp block he is talking about the 2.5" main, wide pan rail block. I'm not sure what mine would be classified as seeing it has a regular pan rail and 3" mains. Like the one Russel Hunt is referring too, when he said he used to bracket race. Probably just considered early DX block.

Oldsguy

The last two posts are examples of factual, informative, and objective statements without name-calling or flaming. Let's keep it that way gentlemen.

raadon

With all due respect, I don't appreciate being called a liar. I never come to this site. I was just looking for some trim pieces for an antique car. I seen a post about a 350 DX so I read it. I offered this block so the guy didn't get ripped by Mondollar. Then somebody jumps in an tells me there is no such thing and I'm misrepresenting what I'm selling. Like I have to prove it exists? I know it exists I GOT THE THING! Prove it doesn't...don't call me a liar and put the burden of proof on me. Come on people grow up!

Oldsguy

He disagreed with you, he didn't call you a liar. Three possibilities, you are right, he is right, or based upon circumstances and experiences both of you made correct statements to the best of your knowledge and there is a disagreement. No name calling or proof is required, let the statements stand.
