Overview

The Dart Race Series Aluminum Small Block Chevy Block is a high-performance engine block designed for Small Block Chevy engines. It features a durable aluminum construction and is available in standard (9.025") and tall deck (9.325" to 9.500") versions. Key features include raised camshaft positions (.391" or .434" option) and spread oil pan rails (.400" per side, .800" wider than stock) to accommodate stroker cranks. Siamesed cylinders allow for bore sizes of 4.000" or 4.125", safely bored to 4.185". The block incorporates ductile iron sleeves, extra thick walls, and relocated oil pan bolt holes. It supports main bearing bores for 350 (2.45") and 400 (2.65") bearings, and includes 4-bolt billet steel main caps with splayed outer bolts. Big block camshaft bearings and dual starter mounts are also integrated. The design includes front and rear external oil inlets, crossover, and restrictor provisions. Scalloped outer water jacket walls are engineered to improve coolant flow, ensuring optimal engine cooling. Coated cam bearings, freeze plugs, and dowels are supplied, and the blocks are available fully finish prepped.

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.
