Dart LS Next

11/18/2013: Borowski Race Engines secures an order for the first two aluminum Dart LS Next blocks due in early 2014. Iron LS Next blocks are in stock.

• New RMR Alloy in Aluminum Models
• 9.240 Deck Height
• Barrel Length: .375 longer than stock GM
• Max Bore: 4.185
• Optional .937 Lifter Bore
• Aluminum Pricing: TBD

Recent customer that brought in a LS2 for a rebuild: "Seeing them side by side, the Dart block is clearly a better piece - even from a distance."

• Dart Fixed the Weak OEM Side Skirt and Main Webbing. Other aftermarket block manufacturers have perpetuated the flawed GM design. Example pictures here, here and here.
