Products - Short Blocks

Mast short blocks are hand assembled by some of the best engine builders in the country using the best components available.  We start with a brand new block that is thoroughly cleaned and deburred.  The blocks are then honed and decked to proper tolerances.  After another thorough cleaning the short block is assembled and ready to ship.  We take pride in our work and are proud to offer a great foundation for your next build!
