BluePrint Engines 427 c.i. GM LS Compatible - Base Dressed - Fuel Injected (PART #BPE-PSLS42781CTF)

Feeding this beast is a cast aluminum LS3 intake manifold, matched with high-performance injectors and a fuel rail kit. The drive-by-wire throttle body offers modern precision, and the LS swap oil pan, water pump, and gas pedal round out the essentials for seamless integration. Tying it all together is the Holley Terminator X Max system, providing advanced engine management and tuning capabilities. This setup isn’t just built—it’s engineered to dominate. The 2-piece BluePrint low profile intake manifold is perfect for factory or low angle hood designs and works great from 2200-8000 RPM range.

The 2-piece design is perfect for periodic clean up or intake manifold porting and is capable of handling up to 600 horsepower.
