Bullet Race Engineering Billet Honda B-Series Engine Block

Available for Order


If you are looking for the ultimate foundation for your B Series build, you have found it.

A building is only as good as the foundation it’s built on, and the same goes for your high output engine build. The Bullet Honda B series billet block has been engineered to deliver reliability in 1700hp environments.

This product has vastly improved block rigidity and improved deck thickness over the stock unit. Distortion of cylinder bores and crank tunnel is dramatically reduced through increased material thickness and a Bullet 4 bolt main cap system.

This product requires minimal modifications to directly replace the standard block.
