Drop in Big Horsepower with a BluePrint Engines Pro Series LS Crate Engine

With over 20 versions to choose from, it will probably take you all day to pick the right BluePrint Engines Pro Series LS Crate Engine for your project car. In the end, it’ll be well worth the effort the first time you hit the gas pedal.

Available in 376 C.I.D. and 427 C.I.D. displacements, the Pro Series LS engines are built with BluePrint’s excellent cast iron block. Features include six-bolt mains; extended 5.75-inch cylinder skirts for added piston stability at BDC; priority main oiling; thicker deck faces for extra rigidity; and an improved water jacket design for better cooling. BluePrint even added provisions for an external oil pump/dry sump oiling system. 

The Pro Series LS Crate Engines are available with a GM plastic intake manifold and drive-by-wire throttle body or a fabricated aluminum intake manifold with drive-by-wire throttle body. They are available with a polished or black accessory drive, or you can get one without an accessory drive if you want to choose your own.

All dressed engines come with:
• Fuel injectors and rails
• Coil packs, ignition wires, and spark plugs
• Rear-sump oil pan for LS swaps in 1955-85 rear-wheel drive vehicles
• Harmonic balancer, water pump, valve covers, front and rear covers

Want more choices? You can get a Pro Series engine with a complete engine harness, GM ECU, drive-by-wire throttle pedal, and sensors. If you just want a long block without all the accessories, you can get one of those too. And if you like blowers, there are three with Magnuson TVS2650 superchargers and Holley Terminator X Max Gen IV engine management systems.

Like all BluePrint crate engines, Pro Series LS Crate Engines come with a dyno results sheet and are covered by a 30-month/50,000-mile limited warranty.
