DART LS Next Iron Block 4.125 Bore / 9.240 Deck With Steel Main Caps

DART LS Next Iron Block 4.125 Bore / 9.240 Deck With Steel Main Caps, Dart LS Next cast iron bare blocks integrate the robust heritage of a traditional Chevy small block with the performance potential of the late model LS engine architecture. The blocks are designed to rectify some of the former LS's more noticeable shortcomings on the bottom end—while still supporting high-flow and efficient cylinder heads developed for Gen III and IV platforms. They're available in multiple engine block styles, including stock/OEM standard deck and aftermarket.
