FAQ
What power level is this “Premium Stock Plus” box designed for?It’s intended for stock to mild builds prioritizing OE drivability and longevity, with premium fasteners and bearings for improved reliability. For large-power goals, consider a Stage 1/Stage 2 Builder Box.
Does it include machine work?Yes. The block is torque-plate honed to blueprint spec, and the rotating assembly is balanced. Final clearance checks and assembly are performed by the installer.
Are gaskets included?A lower gasket set is included. We link additional lower sets and other 12V gaskets above for convenience when doing a complete refresh.
Do I need to address the Killer Dowel Pin (KDP)?Yes—on 12V engines the KDP can back out and damage timing gears. Install the included KDP fix during timing cover service (see our KDP tab in Recommended Parts).
