Borowski Race Engines, Inc. has been the leader in LS Next engine builds since Dart’s original release of the Gen 1 iron block. We received 3 of Dart’s first batch of 25 blocks. All three of our finished engines ended were subsequently featured in Engine Labs on-line magazine. Since that time, we have built them boosted, sprayed; even boosted and sprayed like the one in the video. The killer twin-turbo 427ci LS7 in the main photo was featured front and center at the Dart booth during PRI2014.
We use these super-stout pieces because we believe they are light-years ahead of either factory or competitive after-market LS blocks as platforms for making >1,000 hp engines. You can read what Dart says down below.
Since getting our first LS Next blocks, we have also been at the front of the line for the Gen1 aluminum, Darton MID sleeved, LS Next2 and SHP variants of the LS Next block family. Within this group, we have built engines using numerous machining upgrades such as 0.5” head bolts and piston oilers to name a few. We know LS Next! If you are thinking about big power, you should talk to us.
Gen1 LS Next blocks come in the following configurations:
Cylinder bores: 4.000” and 4.125”
Deck height: 9.240” and 9.450”
Lifter bores: 0.842”, 0.874” and 0.904”
You can order them “as-is”, or have us finish-machine them for you. We can also hook you up with any or all of the upgrades we use in our engine builds. In fact, we can supply you with anything from unopened-in-the-box to a complete crate engine either fully assembled or as a “build-in-box”. Because we are engine builders with an LS Next focus, we have inventory of virtually everything needed to put together complete LS Next engines in a range of designs. Many of the high-end parts in our inventory have a 4 – 6 month lead time from the manufacturers so we may be the only place to buy them.

Here’s what Dart says:
Designed from a clean slate approach the LS Next Iron block has addressed the shortcomings of the LS platform and is the ideal candidate for hot rodders, drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts. By utilizing conventional style main caps and oil pans with LS rotating assemblies and related components, Dart has addressed the windage and oil control problems which result from the factory LS engine’s separated crankcase bays.
