As Merlin Pro pointed out there can be and will be parts that slip past QC. It's no different with the LSX blocks.
Any and all problems that we've seen in the field, like the aforementioned main cap issue, are single isolated cases. To my understanding his situation is being resolved with GMPP at Weber. PM me if this is not the case.
In any manufacturing process things can change. When you start to see patterns it's prudent to stop and take a good look to fully understand why. At that point, revisions can be incorporated in the process to improve quality or even functionality if warranted. The number of issues seen on the LSX were few, but still it was too many considering the use that these component can and will see in their lifetime.
The issues that halted the shipment of the LSX blocks were all discovered during QC inspections during final casting inspections as well as initial machining processes. None those blocks were sold, and GMPP felt it was better served to their customers to stop machining and shipping and make the necessary changes. Just like World Products, their reputation is much more important than shipping product just to say they are shipping and selling product.
Now that all issues have been resolved the LSX blocks will be shipping the first week of March

Robin, have any LSx blocks failed at the track?
This guy posted it happened at the LSX shootout:
"I've got one on backorder. I deal with Ken Casey here in Denver, who has been affiliated with GMPP for years, and apparently has contacts he speaks with. I spoke with him today to check the status of my block, and he told me they should be released in three weeks. The problem was a flaw in the casting, that was allowing a crack to appear in one of the cylinder bores. He also said the problem showed up at the LSX Shootout. I'm gonna turn it into a 434!!! "

They require there own covers and cam plates, which are an extra cost on top of the $4600 block!!!
I was all set on buying a 427 Warhawk, until I was given a quote from a couple vendors and saw the price of all the Warhawk specific stuff. To take full advantage of the Warhawk block (6-bolt heads) the extra parts end up being about another $800 so you will have OVER $5000 in just the block.
I really wanted the Warhawk block, but I only budgeted around $4k MAX for a block and covers.
Other than that I think the blocks accept all the other components.

I guess I'd really only have to spend an extra $3,000 than, because the LSX blocks are around $2,000. So thats not so bad. But I'd still rather have an LSX, no sleeves to worry about and its a much stronger block.

LSX blocks are being shipped as we speak. I know some went out last in the past wek or so and more are being shipped now.
I assume that dealers are filling back orders first. Let me ask where you might find one.
Robin
Edit
Oops, just found out some blocks have shipped, but the big numbers will ship in a week or so.

Merlin, here's the thread on the dropped liner:

Thank you for that link from January. We are investigating that right now but no one knows of this problem from Australia.

I saw that post. It's amazing all the stories that are being passed around.
I was at the LSX Shootout, I didn't see or hear about (then or now) any failures of the LSX Block.
There is nothing wrong with the cylinder walls. No thin areas or cracking. I did hear about one that has a issue with the casting, but it's not related to the recent shortage of the blocks.
I have attempted to run down every rumor or report about issues with the LSX blocks. With the internet, one issue turns in to 5 then the next thing you read is that there are massive failures. I can count on (less than) one hand the number of problem blocks. Trust me, if your builder has been at this for any length of time they have seen one or two parts that were not able to be used. This goes for every type of product, not just blocks.
We have learned a bunch about the blocks in our testing. We continue to look for ways to make all of our products better. Building a high horsepower combination isn't a job for the inexperienced builder. The LSX block is a great foundation to begin with. We are not going to sell a small run of bocks prepped to run in excess of 1000 Horsepower. You need to consult with someone who has the experience to build your engine properly.
Brian Thomson has a twin turbo LSX on his dyno right now. It is in excess of 400 cubic inches. With just a little over 25 pounds of boost it makes over 2000 horsepower. We are not talking about a 1 hit wonder dyno queen. Brian has dialed the boost back to stay just over the 2000 horsepower goal.

Now that is awesome, what took the industry so long to do this. I asked about this 6 years ago.
Merlin,
Is the WarHawk a block that will except 100% of the factory accessories, sensors, wires, plugs, etc.........? Just pull the old factory block out and drop the WarHawk in and bolt everything back together?
If not, what has to be fabbed or what special parts are needed?

The short answer is yes, everything bolts up. Here is the link to our I-sheet showing the relocations of sensors, but they'll all fit/work.

Robin,
"I saw that post. It's amazing all the stories that are being passed around."
Thank you for stating precisely and briefly what I tried to explain in post #28. Tony Mamo has expressed similar thoughts in the past on here.
You comments about QC are also to the heart of where I was going.

I am now talking with Weber Racing about an LS2 block with new sleeves, billet mains, and there 6 bolt addition. I'm thinking that the cost to do all of that to a stock LS2 will be about the same as a Warhawk, but I'll wait and see when he gets my quote done.

The concerns with my Warhawk block are being addressed by World Products. I may have jumped the gun when I said that I was unsatisfied with the block on 2/18. Unfortunately I left today for an extended business trip and was upset knowing that I may have to postpone prior arrangements with my machinist, which is snowballing to back me up with my cage/motor plate fitting when I got back. I am sure that everybody that ever built a car from the ground up can relate to a situation like this.
There are numerous members that have inquired about the concerns that I have had, and I have not discussed these with them. I am satisfied with the explanation from World Products and have chose that I am not going to provide information that may be misconstrued without a proper explanation. There is already too much misinformation floating around the internet.
I am extremely happy with the way World is handling the situation. There customer service is second to none. Merlinpro has been an excellent source of correct information regarding the Warhawk, and great liaison for World.

Don't allways believe what you read,I know its been frustrating to me at times,I have personally invested into one of these blocks and have probably asked my machinist so many stupid questions as a result of these types of posts.But you also "just don't know"these days and it is good to ask!

Thomas,
Thanks for making this explanatory post to the forum. I appreciate the kind words. We will continue to communicate privately until your concerns are resolved.
Supersub makes an excellent point-it's always good to ask.

The last mount bolt hole to bellhouse flange measures 14.250" on Warhawk and SBC. You should have no trouble and positioning should be very close to exact. Just pay attention to your rear trans mount and driveshaft length as a precaution.
Thanks for posting all the acutal facts on this issue! A buddy of mine wants to buy one of the LSX short blocks from a sponsor here & we've heard about the issue but had no data. We feel better now......

Is a LQ4/LS2 iron block considered a big block or are all LSx block ie aluminum and iron all small blocks? I have heard great things about the Iron 6.0L that is what i am looking to do as a project.
