Overview

The ATK SP93-G4 is an LS 370CI Short Block featuring -3.2cc flat top pistons and a 24-tooth crankshaft. It utilizes a seasoned 6.0L Iron Gen IV block with a 4.030” bore and 3.622” stroke. Key internal components include an OE reground 3.622” internally balanced 24 tooth crankshaft, Scat 4340 forged I beam 6.125” rods with ARP 8740 bolts, and Wiseco 2618 forged pistons. Compression ratios vary from 9.7:1 to 10.6:1 depending on head chamber volume. Camshaft bearings, freeze plugs, and oil galley plugs are installed and sealed. Recommended components include an internal balance balancer, internal balance flex plate/flywheel, .051” head gasket (or per application), and a Melling #10295 high-pressure oil pump. It is recommended to use 10W40 non-synthetic oil for the first 3000 miles and a Wix or K&N oil filter.

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.
