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
