Cross Bolted Small Block Chevrolets

2011 n19 adj
These are the ultimate Small Block Chevrolet aluminum blocks. Our blocks are made from special forged aluminum billets. This means that our blocks are stronger than any cast aluminum blocks. On the 2010 we have incorporate a cross bolt main cap design to further strengthen the bottom end of the block.

The 2010 is the ultimate Chevy small block for high horsepower applications with cross-bolted main caps. This block was primarily designed for serious SBC racers, and is the only block for blown alcohol and blown nitro SBC racers. It can also be used for large displacement nitrous small blocks. The block is designed utilizing the rocket block platform.
