This thread is for you all to learn about and ask any questions you have about the LS NEXT & SHP LS NEXT blocks.

If you are building something powerful, choosing the right engine block is one of the most important choices you will make. While LS enthusiasts have done amazing things with stock components, the stock block has its limitation and shortcomings.
We looked at these weaknesses and shortcomings and designed a whole new block that would give the LS platform the benefit of our decades of racing experience.

We have also created several different versions and options for our LS blocks. So, if you have questions on which one might be right for your application, ask away.

Here are a few key photos of the standard LS NEXT aluminum block and some of the key features:
