Billet Engine Monoblock Optimised for M21

Produced from a single piece of premium aluminum, the Serpent 902341 Engine Monoblock is a recommended upgrade for M21 units fitted to Serpent 710 and 950 cars. It provides a neat aesthetic and increases rigidity around the crankcase to reduce stress.

Improved Heat Control and Stability

The monoblock incorporates additional material and cooling fins to boost heat transfer away from the crankcase, aiding steady running temperatures. Its mass distribution contributes to a lower centre of gravity so the vehicle remains composed through high-speed sections. Precision CNC work ensures engine mounts stay accurately positioned for dependable operation.

Specifications

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

Ideal for drivers aiming to tighten tolerances, this monoblock enhances cooling and crankcase stability to support reliable engine performance.

Does this replace the stock crankcase?

This monoblock complements the M21 crankcase and replaces the external housing where applicable. It is engineered to work with M21 dimensions rather than serve as a universal replacement.

Any setup advice after fitting?

After fitting, confirm engine alignment and check for any interference with the chassis or pipe. Run a brief testing session to monitor temperatures and make final trim adjustments if required.

Will it affect engine service intervals?

Improved cooling can help reduce thermal stress, but normal service and inspection schedules should still be followed to ensure long-term reliability.
