SuperCharged LS3 376CI 720HP

The LS3 376CI SuperChraged crate engine is designed to look cool and produce 720+HP. This package design will fit almost any early hot rod. We will custom paint the engine block, oil pan, timing cover, water pump, and valley pan to the color of your choice at no additional cost. The FiTech self tuning Ultimate LS unit is a neat minimal wire installation that will be trouble free. The polished aluminum valve covers are a standard feature in this design to keep the yesteryear look going. This engine package will also arrive with a custom made bracket to relocate coil packs for an added clean install look. We can also outfit this engine with a serpentine belt kit if you would like.
