Our Stage 2 motor is the largest HP/cost to be had on the market. This motor is offered as an entry level with upgraded Manley Turbo Tuff rods and pistons, which give power outputs up to 700hp. We will provide a hard copy spec sheet and blueprint with this motor, and if requested an electronic copy. Our goal is to provide the customer, you, with entry to a level of engine building normally found in super cars and race teams. Our goal is your success, we are not afraid of any problem, and will assist you with any questions. Something that we do that goes above what is traditionally found in a motor at this price point;
Press Fit Insert with more efficient cooling capacity
Pin the Mains with a press-fit dowel pin
Provide true fully blueprinted motor
Blueprinting, Balancing, and Inspection Notes
We blueprint the entire assembly of the motor to within .0002 of our specs,” we then balance the rotating assembly to 1g. Even though the H4 motor is inherently self-balancing, it is incredibly important to balance your motor to increase the life of your bearings. We have an in-house crank balancer with bob weights to give exacting results. It is highly recommended to run a Fluidampr crank pulley or OEM. Do not run an aftermarket solid crank pulley. All of our inspection equipment is high quality, either from Starrett or Mitutoyo, and is sent off yearly for calibration to a qualified cal-lab.
Brand New OEM Inserted Case Halves bored out to 99.75mm and align honed to exacting dimensions. We pin the mains and use decking plates and fixtures to match the distortion the engine will see during final assembly. Once complete, we deck the completed case halves to create a true plane for your head gasket to properly seat on.
