Dart LS Next Cast Iron Bare Blocks
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. Dart LS Next blocks are back and better than ever! Highlight features of the LS Next cast iron bare blocks include: * Cast with premium cast iron alloy * Conventional style 4-bolt steel main caps * Full main webbing for maximum bottom-end strength * Extended cylinder barrels at the bottom to provide greater piston support for all combinations * Extra-thick Siamese cylinder bores * Blind head bolt holes don't go through into the water jacket * Provision for oil restrictors in the lifter valley * Revised low-restriction priority main oiling system * Pro-Stock/Pro-Mod big block style stepped main oil galley * External oil filter (must be used with stock or aftermarket oil pumps) * Dual starter mounts * Expanded water jacket on #1 cylinder for additional cooling capacity * LSX-style lifter bosses and dog bone provision are provided

Dart Freeze Plugs
Durable steel freeze plugs from Dart work like expansion plugs. As we all know, water expands when it turns to ice, and if the coolant in your vehicle doesn't have enough antifreeze protection, it can freeze and then crack the engine block. Dart freeze plugs are designed to pop out under such conditions to relieve the pressure on the block, thus protecting it against freeze damage.
