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 Valve Stem Seals
Dart valve stem seals are designed to control the lubrication of the valve stem as it slides in the valve guide. Too little oil causes stem and guide wear. Too much oil increases oil consumption and can cause a buildup of carbon, leading to valve seat damage and an early valve grind. Available in different styles and sizes, Dart valve stem seals are just what you need to take control of your oil.

Dart Stud Girdles
Dart stud girdles can help to improve the performance and reliability of engines equipped with stud-mounted rocker arms. Extra-long adjusting nuts are tightly clamped between rigid aluminum bars that prevent stud deflection under high loads. The valve motion more closely follows cam profile, producing more power and reducing breakage. Unlike universal girdles, these valvetrain stabilizers are designed to fit the specific valve locations, valve angles, and valve lengths in Dart cylinder heads. These kits include hardened poly-lock adjusting nuts.

Dart Replacement Valve Springs
Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential.

Use only the valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. These Dart replacement valve springs are offered in single and dual styles to meet their cam requirements.
