Engine Block Clearancing

At Northwest Motor Machine, we specialize in engine block clearancing, the fine-tuned process that makes room for larger pistons, stroker kits, or custom performance builds. Clearancing isn’t just about cutting metal; it’s about giving your engine the space it needs to breathe, move, and perform safely under higher stress.

Our experienced machinists carefully remove material in critical areas of the block, ensuring proper piston-to-wall and connecting rod-to-block clearances without compromising strength or reliability. Every cut is measured, verified, and done with the precision your performance build demands.

Why Choose Our Clearancing Services:

  1. Custom clearances for stroker and oversized piston builds
  2. Prevent interference and piston-to-block contact
  3. Maintain structural integrity while maximizing performance
  4. Ideal for high-performance, race, and restoration engines
  5. Done by skilled machinists with years of experience

Clearancing your block is about unlocking potential safely. Let us handle the critical precision work that keeps your engine strong and your build running smooth.
