Callies Gen II Hemi Wedge Block 4.315 Bore 10.725 Deck — Rough Bore Iron Block

Precision Foundation for Gen II Hemi Wedge Engines

Unlock the true potential of your Gen II Hemi build with the Callies Wedge block. This bare block is specifically designed for builders who require a larger 4.315-inch bore and a 10.725-inch deck height to accommodate custom high-displacement rotating assemblies. Constructed from heavy-duty iron, this block is built to withstand the rigors of competitive racing and high-boost environments.

Technical Highlights:

• Bore Diameter: 4.315 inches (Rough Bore)
• Deck Height: 10.725 inches
• Main Caps: 4-Bolt Main design
• Seal Compatibility: 2-Piece Rear Main Seal
• Application: Gen II Hemi Wedge

The 4-bolt main configuration provides the necessary clamping force to keep your crankshaft stable at high RPMs, reducing bearing wear and increasing overall engine longevity. By starting with a high-quality Callies casting, you ensure that your cylinder walls remain stable under extreme combustion pressures. This block is the perfect starting point for custom stroker kits or high-compression naturally aspirated setups. Its robust iron construction offers superior heat dissipation and structural rigidity compared to factory alternatives.
