The bottom end, or "block" depending on your terminology is the foundation of your engine assembly. EVERYTHING is bolted to the block! It is the heart of your engine, and contains your: crankshaft, connecting rods, pistons, bearings, oil pump, water pump, oil filter, and all of the pieces involved in allowing those components to work together. Building a strong block is important, especially if you are planning to go the forced induction route, as parts selection becomes more important considering you will be hosting a greater horsepower potential than the factory intended.
We offer you a wide variety of choices for your block upgrades, a lot of which we have tried ourselves or have used in customers engine builds, so these products are also highly recommended by us and trusted for not only our engines, but yours as well.
