Every core is treated as an individual build. The engine is fully disassembled so the block, cylinder heads, crankshaft, connecting rods and related components can be cleaned and inspected independently. Wear, damage, and concerns are documented to determine which components can be reused, which require machining and which must be replaced before the build moves forward.

Complete Teardown

The engine is completely stripped so every reusable and replaceable component can be assessed.

Cleaning

Parts are thoroughly cleaned to expose wear, damage and surface condition.

Initial Inspection

The block, heads, crankshaft and related components are checked before machining.

Component Review

Critical components are reviewed against specifications and build requirements.

Build Planning

Inspection results determine the machining, parts and processes required for the build.

Machining requirements are determined by the measured condition of each individual core. Cylinder bores, deck surfaces, main housing bores and cylinder heads are machined as required to restore geometry, alignment and surface finish. Each operation is completed around the final component combination and intended build specifications to create an accurate and stable foundation for assembly.

Block Machining

The block is machined according to its measured condition and final build specifications.

Cylinder Honing

Cylinder finish and geometry are established for proper ring seal and piston clearance.

Deck Resurfacing

Deck surfaces are restored for consistent gasket sealing and correct surface finish.

Main Alignment

Main bore condition and alignment are checked and corrected where required.

Head Machining

Cylinder heads are machined and prepared in-house for final valvetrain assembly.

Critical dimensions are measured throughout the machining and preparation process rather than relying on assumed or nominal specifications. Cylinder geometry, crankshaft journals, bearing oil clearances, piston-to-wall clearance and related component fits are checked against the requirements of the specific engine platform and build configuration. This confirms that the complete component stack-up is correct before assembly.

Bore Measurement

Cylinder size, taper and geometry are verified after the final honing process.

Crankshaft Inspection

Journal condition and dimensions are checked before the crankshaft enters assembly.

Bearing Clearances

Oil clearances are measured to confirm correct bearing fit throughout the rotating assembly.

Piston Fit

Piston-to-wall clearance is verified for the selected piston and intended application.

Final Verification

Critical dimensions are checked again before components are approved for assembly.

Final assembly brings together the completed machining, verification and component preparation. Bearings, crankshaft, connecting rods, pistons, rings, camshaft, timing components and cylinder heads are installed in sequence using the required clearances, fastener procedures and engine-specific specifications. Critical fits, rotation and component relationships are checked throughout the assembly process.

Rotating Assembly

The crankshaft, bearings and connecting rods are installed using the verified build measurements.

Piston Installation

Pistons and rings are prepared and installed with the required orientation and clearances.

Camshaft & Timing

Camshaft and timing components are installed and checked before the engine is closed up.

Cylinder Heads

Prepared cylinder heads are installed with the correct sealing components and torque procedure.

Final Assembly

Remaining covers, sealing surfaces and engine-specific components are completed in sequence.

Before the engine leaves our facility, the completed assembly undergoes a final quality-control review. External components, plugs, covers, sealing surfaces and build-specific details are checked for completeness, and the rotating assembly is verified for smooth movement. Openings and machined surfaces are then protected before the engine is secured in its shipping container with the required build documentation.

Rotation Check

The assembly is rotated and checked for smooth, consistent movement.

Visual Inspection

External surfaces, plugs, covers and sealing points receive a final visual review.

Build Review

The completed configuration is checked against the build requirements and documentation.

Protective Packaging

Engine openings and finished surfaces are protected before the engine enters its shipping container.

Shipping Preparation

The engine is secured and prepared for pickup or delivery with the required paperwork.
