Description

The Chevrolet Performance 1986-Later Style 383 Bare Engine Block is a production-based component designed to provide strength and accuracy for engine builds. It features four-bolt main caps for enhanced durability and a 1-piece rear main seal. This block is ideal for street machines and mild-to-moderate performance builds, supporting a maximum of 450 horsepower. Constructed from cast iron, this bare block is torque plate-honed for superior ring seal and compression. The lifter valleys are machined to accommodate either hydraulic roller or flat tappet valvetrains, and it is clearanced for a 3.800" stroker crankshaft. The cylinder walls maintain a production-spec thickness, and the non-siamesed bores promote effective cylinder-to-cylinder cooling. Key specifications include a 9.025" deck height, a bore range of 4.000" to 4.030", and a wet sump oiling system. This engine block is specifically noted for use on pre-pollution controlled vehicles, defined as 1965 and older U.S. manufactured California certified vehicles, and 1967 and older U.S. manufactured federally certified vehicles. It is designed for pre-1976 street vehicles and off-road applications. Vehicle fitment includes C/K models from 1988-1998 and C10 models from 1960-1987.

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.
