CISON V8-440 OHV 44cc Small-Block V8 Gasoline Engine Model Kit Full Set
Hero Section: The "Small-Block" Legend, Reborn on Your Desk
If the Flathead was the pioneer, the OHV "Small-Block" was the revolution. The CISON V8-440 OHV brings the golden age of American muscle cars right to your fingertips. This isn't just a model; it is a 44cc, 10,000 RPM mechanical beast waiting to be unleashed. With its high-performance Overhead Valve design and stunning electroplated orange finish, this engine captures the soul of the drag strip. Whether you are an RC builder looking for the ultimate power plant or a collector seeking a kinetic masterpiece, the V8-440 OHV delivers a visceral experience of speed, sound, and precision engineering.
Why Choose the CISON V8-440 OHV Kit?
- High-RPM Muscle (10,000 RPM): Unlike its Flathead cousin, this OHV version is built for speed. With a redline of 10,000 RPM and approx. 4.8hp, it screams with the ferocity of a racing engine. It offers significantly higher torque and power output, making it a true powerhouse for large-scale RC models.
- The "Full Set" Advantage: We know you want a complete experience. This package includes not just the engine kit, but also a premium metal base, a radiator, and dual fuel tanks. It is a turnkey solution designed for display and operation straight after assembly.
- Precision 5-Axis CNC: Perfection is in the details. The cylinder block is machined using aerospace-grade 5-axis CNC technology with a repeatability of 0.005mm. This ensures that every piston, valve, and gear fits with surgical precision, resulting in smooth operation and long life.
- The Ultimate DIY Challenge: There is no greater satisfaction than building a V8 from scratch. Assembling the 5-point supported crankshaft, installing the hardened connecting rods, and timing the valves is a journey that deepens your understanding of mechanical engineering.
Technical Highlights: Engineering Deep Dive
- Robust High-Speed Internals: To handle 10,000 RPM, the engine features a reinforced 5-point supported crankshaft and hardened wear-resistant connecting rods. This structural rigidity prevents flexing under high load, ensuring stability at top speed.
- Independent Lubrication: This engine features a true independent lubrication system with a dedicated oil sump and a reserved position for an oil filter. This critical feature protects the bearings and crankshaft, offering superior durability compared to simple mixed-fuel engines.
- Advanced Cooling System: A double-layer gear water pump drives the coolant through the included radiator, effectively managing the heat generated by the massive 44cc displacement during extended runs.
- High-Performance Ignition: The engine utilizes a mechanical distributor paired with a high-frequency CDI (42,000Hz), ensuring that all 8 cylinders fire in perfect sequence, delivering that signature smooth yet aggressive V8 idle.

Usage Scenario: The Roar of Success
You’ve spent the week meticulously assembling the kit. The orange block sits proudly on the metal base. You connect the radiator hoses and fill the dual tanks. You press the start button. The starter motor whines, and then—EXPLOSION. The V8 roars to life, settling into a lumpy, aggressive idle. You blip the throttle, and the RPMs rocket to 10,000, the sound filling your workshop. You didn't just build a model; you built a monster.
Important Tips from the Workshop
- Lubrication is Mandatory: This engine uses an independent lubrication system. You must fill the oil sump with the recommended 10W50 oil before starting. Running it dry will destroy the bearings instantly.
- Break-in Procedure: With new piston rings and high-performance tolerances, run the first few tanks of fuel at moderate RPMs (under 5000) to allow the rings to seat properly against the cylinder walls.
- Battery Requirement: To turn over this high-compression 44cc engine, a high-discharge 2S or 3S LiPo battery is recommended for the starter.
- Safety: This is a powerful gasoline engine. Operate in a well-ventilated area and keep hands clear of the flywheel and belts.
