The ZL402 LS1 based iron stroker short block is loaded with the kind of top-quality hardware found in short blocks costing much more. It was the first choice for the experts at Car Craft magazine, who took an off-the-shelf ZL402 stroker motor and produced over 575 horsepower, naturally aspirated.

SLP's ZL402 is built around a new GM LQ9 Gen III 6.0 liter block, a 4.00" forged steel crank, and 4.00" forged aluminum pistons.

This package is sold only in short-block form, minus manifolds, camshaft, oil pump, and other equipment. The advantage of this approach is it allows you to pick a combination best for you. SLP also sells heads and cams, and we'd be happy to recommend the best combination for you.

Although designed primarily for use in late-model F-Bodies and Corvettes, the ZL402 also makes a great choice for street rods, muscle cars, and trucks. Best of all, it's sold outright, eliminating the shipping hassles and expenses of core returns.
