Overview

Its patent-pending tab-and-slot design provides accurate mounting positions for engine accessories and bolt-ons. This lightweight block comes disassembled for easier shipping and storage.
Show original supplier description
Its unique tab-and-slot construction creates a rigid representation of the engine block, superior to bolt-together types. This lightweight design comes disassembled for convenient shipping and storage, and can be easily positioned by hand, eliminating the need for a crane. Its steel construction also resists welding heat, enabling custom motor mounts to be fabricated directly on the block, unlike foam alternatives. The Swap Block includes hardware for exhaust, motor mounts, bellhousing, oil pan, and water pump, simplifying the engine placement process for your build and saving time, money, and increasing safety.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
