Description

The Chevrolet Performance 19432779 is a new Vortec HD 350 L31 crate engine, designed as a replacement for 1996-2002 GM vehicles. This engine features a 5.7L/350 cubic inch displacement, a 4.000-inch bore, and a 3.480-inch stroke, contributing to a 9.3:1 compression ratio. The engine block is constructed from cast iron and boasts a robust 4-bolt main design with a 1-piece rear main seal for durability. It is internally balanced and equipped with a forged 1053 steel crankshaft. The camshaft is a hydraulic roller type, specified as OE, with an intake lift of .414" and an exhaust lift of .428". Valve duration at 0.050 inches is 191° for the intake and 196° for the exhaust, with a firing order of 1-8-4-3-6-5-7-2. This crate engine offers 250 horsepower at 4600 RPM and 330 ft-lbs of torque at 2800 RPM. It's important to note that current small block accessory drive kits may not properly mount due to missing casting bosses on this engine. The engine comes with a 3-year/100,000-mile warranty from Goodwrench.
