This is a brand new engine, never run. 440 c.i. all aluminum, fuel injected, compression 10.5:1, natural aspiration, built for low rpm high torque, suppose to produce 600 hp. Engine is a tall deck Dart with 4.25 inch stroke and 4.25 inch diameter forged pistons. Heads are Dart Pro-1, Lunati crank, JE pistons, Crane hydraulic roller cam, Weaver sub-oil pump, Accel base modified intake plate, stainless runners 36 inch in length, custom aluminum plenum, Oliver rods, Trend push rods, ATI harmonic balancer, and much more. Balanced and blueprinted. This engine cost $19,759,00 to build. Will sell as is for $14,000, or if you just want the short block with heads and covers, will sell for $12,000.00. It was built for an aircraft, but now I need a big block instead. This engine can handle a blower if needed. Good for custom car or boat. If interested I will fax cam specs. and work order to you for all parts and labor that went in to it. If you call please leave a message or text and we will get back to you. Bridget will be answering.
