Description

The Chevrolet 19432779 is a brand new, complete long block crate engine designed as a heavy-duty replacement for worn 350ci Vortec engines in approved GM applications from 1996 to 2002. This engine utilizes all new cylinder head and block castings, a forged steel crankshaft, and features a 4-bolt main block construction for enhanced durability. It is roller camshaft ready and mechanical fuel pump capable, though it does not include a camshaft eccentric for a mechanical fuel pump. This Vortec HD 350 L31 engine delivers 250 horsepower at 4600 RPM and 330 ft-lbs of torque at 2800 RPM. It includes new valve covers, oil pan, timing cover, and harmonic balancer. The engine is precision machined and assembled in the USA, with GM OE part validation and end-of-line testing for torque, compression, and oil pressure. A limited 3-year, 100,000-mile GM warranty is provided when installed in an approved GM application. For fitment verification, contacting the seller with your vehicle's VIN is recommended. Please note that this engine is not intended for marine usage. It replaces GM part numbers 12691672, 12530283, and 12681431.

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.
