The ZL402 LS2-based aluminum short block builds on the success of SLP's 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.
Built entirely from brand-new parts.
Sold outright, no cores required!
