CAST IRON BIG BLOCKS

The legend just got better! These may look like the same street blocks that set the standard at drag strips for a generation, but they have a whole new attitude. Just check out these features:

• 100% CNC Machined for Accuracy and Quality
• Brand-New Castings Made from High-Nickel Alloy Cast Iron
• Thicker Deck Surface for Improved Rigidity and Gasket Sealing
• Ductile Iron Main Caps; Cross-Bolted on the Three Center Caps on all 440 Blocks
• Stock 10.72" Deck Height Allows for Standard Components
• Machined to Accept All Standard Production Pieces

Mopar Siamese-Bore Big Blocks are specifically designed to be bored larger. Mopar still recommends that you sonic check each block if you exceed as-shipped bore diameters.
