Solid Aluminum Monoblock Built for M21 Power

Forged from a single piece of high-quality aluminium, the Serpent 902341 Engine Monoblock provides a robust upgrade for M21 power units installed in Serpent 710 and 950 cars. The component delivers a neat finish while reducing crankcase stress and keeping mounting points true.

Heat Dissipation and Stability

The monoblock features added mass and finning to increase heat transfer away from the crankcase, helping maintain steadier operating temperatures. Its form also contributes to a lower centre of gravity for improved stability at speed. Accurate machining guarantees correct engine mounting alignment for smoother operation and extended service life.

Specifications

  • Material: High-grade aluminum
  • Compatibility: Serpent 710 and 950 models
  • Finish: Silver anodized for M21 engines

A practical choice for racers wanting to reduce crankcase flex and improve cooling, this monoblock helps keep M21 engines performing consistently.

Will this fit smaller or larger engine types?

No. The external dimensions and mounting points are specific to M21 engines. For other sizes, look for the matching monoblock designed to those dimensions.

How should I maintain the monoblock?

Keep fins clear of dirt, inspect mounting fasteners regularly and avoid over-tightening. A light polish can prevent corrosion and keep the anodised finish looking good.

Does it change engine height or drivetrain alignment?

The design maintains correct mounting geometry for the M21 and should not alter drivetrain alignment when fitted correctly, but verify fit on your specific chassis during installation.
