BBC 454ci 400 Hp Marine Crate Engine

454ci 400+Hp BBC Marine Crate Motor

Marine Crate Motors are new direct replacement units for your marine needs. Built for any type of marine application where long term reliable power and performance is needed. Blocks are prepared on our state of art Centroid 4-axis machining center that corrects block dimensions to blue print perfect. Each engine is dyno tested and tuned, not some phony guess work on real power. Expect and receive the best in product, power, price and performance. A lot of engine builders in the industry just re-manufacture everything possible. You are really just getting old parts that have been recycled. The block is the only item reused!
