Anyone thinking about rebuilding their old 350 Chevy Small Block V8 should instead consider this new, budget-friendly alternative from Chevrolet Performance. The latest V8 is ready for easy transfer of the intake and other accessories, keeping costs low, while also adding in a few modern features as well.
“Chevrolet Performance’s new 350/265 Base engine assembly offers an economy-minded alternative to rebuilding Gen 0-type 265-400-cubic-inch Small Block engines,” the automaker states. “It is assembled with all-new, premium components, including a brand-new block with four-bolt main caps – a strength-enhancing feature most original and core 350 engines don’t have.”
The new Chevy Small Block V8 comes with powdered metal steel connecting rods and cast aluminum pistons, with an 8.0:1 compression ratio that’s “suited for performance at all elevations.” There’s also a hydraulic camshaft, while the engine is delivered with the timing cover and oil pan for easy component transfer and lower overall cost.
Output (when equipped with intake manifold P/N 10185063 and a Holley 650 carb, both of which are not included) is rated at 265 horsepower at 4,300 rpm and 351 pound-feet of torque at 3,300 rpm. The maximum recommended engine rev limit is set at 5,100 rpm.
The block also comes with a pre-1986-style design and a two-piece main seal. The crate engine requires the starter, induction system, spark plugs and wires, water pump, fuel pump, and distributor in order to complete the build. Chevrolet Performance says the new Chevy Small Block V8 is also incompatible with the Chevrolet Performance roller lifter assemblies.
The new Chevy Small Block V8 is not intended for marine applications, and is not recommended for vehicles above a 6,000-pound GVWR. Chevrolet Performance also recommends the use of 5W-30 Mobil 1 engine oil. The engine is intended for competition use only, and includes a 24-month / 50,000-mile limited warranty as well.
