LSNext Blocks have arrived @ SDPC!!!
We have received a large shipment of the newest LS block available. This is the Dart Machinery LSNext block. We have not yet started a build with one of these, but we are excited to get to work on one soon.
Here are some pictures of one that's in stock here, as well as some highlights from Dart. At the bottom you'll find part numbers and pricing. We don't yet have more oil pan spacers or block completion kits in stock for pictures, as we have shipped what we received to customers already. I will come back and update with those as soon as we get the next shipment.
Dart’s LS Next block is the first significant change in the architecture of the LS engine platform. By eliminating the “Y-block” design and utilizing conventional style main caps and oil pans, Dart has addressed the problems resulting from the LS engine’s separated crankcase bays. Windage is greatly reduced, resulting in increased power along with a much stronger main web area.
You'll notice some "odd" differences from what you're used to. Older SBC guys won't find most of this odd and will recognize some things. You might also have some questions, which are quite welcome.
You'll notice the different cam retainer plate
Water jackets are revised.
You aren't running stock lifter guides in this block. LSX guides or tire bars.
These have press in freeze plugs.
The barbell hole is plugged.
This will use stock front and rear covers.
We know how the stock block and parts handled all of the passages under the covers. We will have to get the completion kit in here to see what Dart does in those areas. Especially with the deletion of the stock cam retainer that connected the two front oil passages.
There is no provision for a Gen 3 cam sensor. You will have to run the Gen IV front cover and sensor.
There is no passage that supplies oil to the stock location in the valley cover for the oil pressure sensor. There might be a passage you could drill into, we are not certain at this time. You may have to run the sensor in an alternate location.
Note the pads for a starter on either side of the block.
Block with 4.100 bore = Dart 31837111 $2469.95 with free shipping
Block with 4.125 bore = Dart 31837211 $2469.95 with free shipping
Block completion kit = Dart 32000016 $129.95
Oil pan rail adapters = Dart 62230001 $329.95
Moroso LSNext oil pan = 20144 $534.99
Required pickup tube for that pan = 24144 $129.95

You are correct it is a good benefit to the LS blocks but having a splayed cap block is also a super strong setup. Its not like a standard 4 bolt main sbc block. The splayed caps allow for a lot more material between the bolt holes. Plus pulling the mains out of the block eliminates the problem of windage and bay to bay breathing problems...

I am sure these are nice as hell but I don't see any use for them. Guys are making stupid power with stock blocks and I don't think I have ever seen one fail. I am sure some have but few and far between from what I have seen.
Maybe I am missing something but looks like about 3500 for a block that is ready for a rotating assembly?
Sorry to be negative but I don't see any problems being solved with this "next" generation.

Im sort of confused as to how you could run the stock front and rear cover. What oil pan does this take? If it takes a stock oil pan there must be some sort of oil pan rail extension that goes on these.
I went up and looked. I didnt see the moroso oil pan before, and there are rail extenders. Well that answers that.

In the picture with the valley plate, it looks like there is no way for an oil pressure sensor to get a reading. Is this true or am I missing something?
Also, getting to the lifters without pulling the heads! Awesome!

Wow, that thing looks beefie!!! Interested to see how the other parts tie it together.
Do they require special head gaskets or can you use any LS type head gaskets???
I see they didn't drill the block for a top oil sensor. Does it use an alternate location???
Does it have a place to mount the crank sensor and knock sensors???
