BluePrint BP38318CT1 S/B Fits Chevy 383 Longblock Crate Engine

BluePrint's 383 small-block Chevy longblock is listed here as the bare build: the same 436-horsepower, 443-pound-foot rating, still on 10.0:1 compression, but without the intake manifold, distributor, carburetor, or front accessories bolted on. Builders who already own induction and ignition parts, or who want to choose their own, start here instead of the dressed listing.

Core build

• New cast iron block, four-bolt main caps, one-piece rear seal, drilled and tapped for clutch linkage
• Cast steel crankshaft turning hypereutectic pistons on 5.700-inch rods with 150,000-psi bolts
• Aluminum cylinder heads over a hydraulic roller camshaft, 2.02-inch intake and 1.60-inch exhaust valves
• 383 cubic inches of displacement, a 4.000-inch bore paired with a 3.750-inch stroke

Setup notes

BluePrint's own paperwork for this build points builders toward a BPP400L harmonic balancer and a torque converter in the 2,000-2,400 rpm stall range as a starting combination, and the company recommends 91-octane fuel. Treat those as suggestions rather than requirements for your own setup; this listing doesn't include the parts they describe. The engine itself is new, not a rebuild, and BluePrint documents it with a 30-month or 50,000-mile coverage term, whichever comes first for the buyer.

Does it come with an intake or carburetor? No. This listing is the bare longblock, so plan on sourcing your own induction, ignition, and accessory-drive components separately before it can run.
