BLOCKS IN STOCK

As usual, Borowski Race Engines was at the front of the line for the latest Dart LS Next product release. Their LS Next SHP Pro is a major upgrade as it steps their skirted iron block up to the same 220 BHN iron as their original LS Next blocks. That's about a 1/3 increase in tensile strength which is a really big deal. It's such a big deal that we revised our LS crate engine recipes to take advantage of this new product.  As we see it, the superior metallurgy is well worth the relatively small upcharge.

Here is what Dart says:
Dart Machinery continues the evolution of the LS Next platform by releasing the all new SHP LS Next PRO block! Designed for high performance applications, the SHP LS NEXT PRO block is the ideal starting point for drag racers, circle track competitors, off-roaders, and high performance marine enthusiasts. This new superior strength 220 BHN cast iron block features a full skirt design with a priority main oiling system, steel four-bolt main caps with upgraded ARP main studs and provisions for stock and aftermarket oil filter mounting.
