SLP's ZL402

The ZL402 LS2-based aluminum short block builds on the 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 compared to an LQ4/LQ9-based engine.

Although designed primarily for use in late-model F-Bodies and Corvettes, the aluminum ZL402 also makes a great choice for most late-model GTOs, street rods, muscle cars, and trucks. Best of all, it's sold outright, without core charges.

You won't find a higher quality, better value LS2 stroker short block anywhere!


  • Built entirely from brand-new parts.
  • Sold outright, no cores required!
  • 402 CID displacement
  • GM LS2 aluminum 6.0-liter block (includes block plugs)
  • 4.000" Eagle 4340 forged steel crankshaft, balanced to rotating assembly
  • 4.000" Ross 2618 forged alloy pistons with -28.50cc dish (includes new rings and full-float pins)
  • 9:1 compression ratio (nominal; ultimate compression ratio will depend upon heads and gaskets used)
  • 6.125" Eagle H-beam rods
  • Includes new, factory-installed cam, rod and main bearings.
  • Comes with everything required to retrofit into an LS1-equipped car or truck
  • Designed for naturally aspirated use.
  • Assembled to OEM tolerances and specifications.
  • Capable of supporting over 700 hp.
  • Oil pump, camshaft, pans, and plates not included.
