Is the Cummins configurator estimate a final quote?

No. The configurator provides a ballpark estimate for your selected build. A Motor Parts + builder confirms fitment, availability, core details, freight, and final pricing before you order.

Can I configure just a Cummins cylinder head?

Yes. Select Cylinder Head Only to compare the listed head-exchange packages. Review the core requirements and ask the shop to confirm the correct package for your engine.

Do I need an account to request an engine quote?

No account is needed. Choose your configuration, use the quote button to send your build details, or call Motor Parts + to discuss the build directly.

⚠️

Core charge required. All cylinder head exchanges require a $1,000 refundable core charge in addition to the package price — send back your old head in rebuildable condition to have it credited. Heads are crack checked, acid washed, vacuum checked, and receive valve seat repair/replacement and valve resurfacing or replacement as needed.

Please note: Increasing horsepower well beyond factory ratings puts additional stress on the factory transmission, clutch, driveline, axles, cooling system, and other drivetrain and accessory components not included in this engine build. These factory components were not engineered for the higher power levels our Comp and Strip tiers can produce, and their long-term reliability and survivability cannot be guaranteed after a high-horsepower build. We're happy to discuss supporting driveline upgrades — ask your builder for recommendations.
