Product Overview:

Description

ATK HP99C Chevy 350 Vortec Engine, or Stage 3 Engine, is designed for those that are wanting to drop the engine into their project and fire it up. We try to outfit the engine as completely as possible to save you time and headaches. A GM Complete Dress engine typically consists of the Stage 2 build out plus the following: Carburetion, Spark Plug Wires, & Spark Plugs.

Introducing our new Econo 350CI Engine. We take one of ATK's Stock Replacement Remanufactured Vortec 350CI Engines and dress it out to be retrofitted for a Muscle car swap. The Vortec 350 engines are known for their better flowing Vortec Heads and Hyd. Roller Camshaft setup.This engine will come completely assembled as shown minus the fuel pump. These blocks DO NOT have a mechanical fuel pump provision and an electric fuel pump must be used.

ATK specializes in muscle. With the highest quality internal parts and Dyno Proven combinations of every engine built, ATK is able to add the most bang for your buck and back it up with an industry leading warranty.
