| Crate Engine Assembly, ZL402 LS1 Iron Short Block (High Compression) | |||||||||||||||||||||||||||||
|
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 SLP ZL402 stroker motor and produced over 575 horsepower, naturally aspirated. Our ZL402 is built around a new GM LQ9 Gen III 6.0 liter block, a 4.00 inch forged steel crank, and 4.00 inch 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 cylinder heads and camshaft packages, 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 is sold outright, eliminating the shipping hassles and expenses of core returns. You will not find a higher-quality, better value LS1 stroker motor anywhere! NOTE: While placing your order, please specify model year that the 402 will be installed in, and what style reluctor wheel is required. SLPs 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 Iron Short Block Includes the following:
NOTE: SLP STRONGLY recommends that final assembly and installation be performed by an experienced, professional mechanic. Assembly/installation instructions are neither included nor available with this part. This item must be prepaid with a certified check or money order. Please call (763) 390-6385 for more information and a shipping quote. All engines are shipped in a Heavy-Duty crate, $100.00 additional charge applies.
