Compatibility and Fitment

All upgrade options are designed specifically for the Motabas Yen Buick Nailhead Base Engine. The base engine is required to use any upgrade kit and is not included when an upgrade-only option is selected. Final vehicle fitment depends on the donor chassis, firewall, transmission tunnel, suspension, steering, headers, and available engine-bay clearance.

What’s Included

Each purchase includes only the selected option. Select Base Engine to receive the complete base engine and Dynaflow transmission described above. Selecting an upgrade kit includes only that specific upgrade; it does not include the base engine or any other upgrade option.

Scale

Designed as a scale automotive engine system for compatible detailed model builds.
