Unleash classic muscle with modern reliability. The BluePrint Engines BP38318CTC1D is a fully dressed 383 cubic inch Stroker crate engine that delivers a stout 436 horsepower and 443 lb-ft of torque right out of the box. This engine is the ultimate drop-in solution for enthusiasts seeking a massive power increase for their street rod, classic muscle car, or hot rod project without the guesswork of a custom build.
Meticulously hand-assembled and dyno-tested, this crate engine combines a proven 4-bolt main block with a precision-balanced rotating assembly and high-flow aluminum cylinder heads. It comes complete with everything you need to fire it up: a 750 CFM carburetor, HEI distributor, spark plugs and wires, water pump, and a dual-plane intake manifold. This “dressed” configuration means you unbox, install, connect the essentials, and turn the key.
Built for strength and performance, this 383 Stroker features a hydraulic roller cam for crisp throttle response and low-maintenance operation, a high-volume oil pump for critical pressure at high RPMs, and hypereutectic pistons for an optimal balance of durability and performance. This isn’t just an engine; it’s a turn-key horsepower solution backed by a dyno-proven results sheet.

Frequently Asked Questions (FAQs)
Q1: Is this engine truly ready to run? What else do I need?
A: Yes, it is a “dressed” long block. It includes all critical components. You will need to add a flexplate (for automatic) or flywheel (for manual), engine mounts, headers/exhaust, a throttle cable, and hook up your existing coolant hoses, fuel line, and starter. The mechanical fuel pump is included.
Q2: Will this engine fit under the hood of my [Year] Corvette?
A: No. BluePrint specifically notes this engine will not clear a stock Corvette hood due to the height of the included air cleaner and carburetor setup. A low-profile air cleaner or aftermarket hood may be required for some applications.
Q3: What fuel and octane do you recommend?
A: With a 10.0:1 compression ratio, this engine is designed to run reliably on premium 91-93 octane pump gas. Using lower octane fuel may cause pre-ignition (pinging) and potential engine damage.
Q4: What is the warranty on this crate engine?
A: BluePrint Engines typically offers a 30-month/50,000-mile limited warranty on their crate engines. Always confirm the specific warranty terms at the time of purchase, as policies can be updated.
Q5: The specs mention a “raised exhaust port.” What does this mean for installation?
A: The aluminum heads feature exhaust ports raised 0.5 inches compared to standard heads. This is for improved flow but means some stock exhaust manifolds may not bolt up directly. It is highly recommended to use aftermarket headers designed for aftermarket cylinder heads with raised ports.
