Crate-Engine-Full-Assembly "ZL402" LS2 Aluminum Long-Block (High Compression)
Product Description
Crate-Engine-Full-Assembly, "ZL402" LS2 Aluminum Long-Block (High Compression)
The all-new ZL402 Gen IV LS2-based aluminum short block builds on the phenomenal success of our original ZL402 iron short-block. This new package uses the same race proven internals as its iron block predecessor but features the all-new LS2 block for weight savings of over 100 pounds. We've even increased the compression ratio to 11:1 (nominal) - the same as GM's new 500-horse LS7! Although designed primarily for use in late-model F-Bodies, Corvettes and GTOs, the aluminum ZL402 also makes a great choice for most street rods, muscle-cars and trucks. Best of all, it's sold outright, eliminating the shipping hassles and expenses of core returns.
This package is sold in long-block form, including and installed SLP/AFR head-and-camshaft package w/# 51015 camshaft, SLP double-row timing chain, SLP Heavy-duty oil pump, new GM lifters and lifter guides, ARP cylinder head studs and MLS head gaskets. The advantage of this approach is the new ZL402 long-block ships to you already assembled.
NOTE: While placing your order, please specify model year that the 402 will be installed in, and what style reluctor wheel is required. SLP's harmonic balancer/under-drive pulley is required for proper installation (or an equivalent pulley that is properly keyed) a stock balancer/pulley will NOT fit.
ZL402 LS2 Aluminum Long-Block Includes the following: Built entirely from brand new parts Sold outright, no cores required! GM LS2 aluminum 6.0 liter block 402-CID displacement 4.000" Callies 4340 forged steel crankshaft, balanced to rotating assembly (included are the SLP windage tray spacers) 4.000" SLP/Manley 2618 forged alloy pistons with -6.00cc dish (includes new rings and full-float pins) 6.125" SLP/Manley 4340 forged steel H-beam rods Includes new, factory-installed cam bearings; Clevite rod and main bearings SLP 51015 Camshaft SLP/AFR Cylinder Heads SLP 55003 Double-Row Timing Chain SLP 55001 Heavy-Duty Oil Pump New GM Lifters and Lifter Guides ARP Cylinder head Studs MLS Head Gaskets 11:1 compression ratio (nominal; ultimate compression ratio will depend upon heads and gaskets used) Designed for naturally aspirated applications Capable of supporting up to 700+ HP Meticulously assembled by SLP to OEM tolerances and specifications. Includes all necessary accessories for retrofit into a Gen III-equipped vehicle Pans, plates, and covers not included. ZL402 OEM-quality fender badges (pair).

Assembly/installation instructions are neither included nor available with this part. Not compatible with pre-2005 GM knock sensors!
**All engines are shipped in a Heavy-Duty crate, $100.00 additional charge applies**
