Complete 450 hp Engine and PSRU Package available.    SOLD


​This complete package includes the well proven high performance Rodeck Aluminum Block engine based on the Chevrolet small block 350 cu in.  It puts out 450 hp at 5,200 rpm and was used as the test engine in developing the Bull Moose prototype.  While it performed very well, in anticipation of going into production with a Firewall Forward package for Murphy Moose, Super Rebel and other recreational aircraft, a decision was made to use the more readily available LS3 engine for the package we are now producing.  This engine will be sold with a fresh "0" time overhaul and with the low time CAM 500 PSRU by Firewall Forward.  That unit was sent out for an elective inspection at the factory and comes with the remaining 46 months of factory warrantee. The engine has dual MSD ignition boxes, MSD Distributor, all recently overhauled by the factory, dual coils and selector hardware and an all new MSD plug wiring harness.  It comes with a 4 barrel 750cfm Holly carb, with a mixture block for manual mixture control.  It also includes the custom Murphy Bull Moose four into one exhaust headers with ceramic coating in and out for great inner cowling temperature reduction.  Does not include vacuum pump and prop governor. We are able to provide a new engine mount at additional cost. Does include chrome alternator and billet mount. Individual component cost is in excess of $36,000.  NEW PRICE as described above is ​$21,500 with fresh overhaul on engine. Will consider offers or trades.

The ability to change the pitch in flight is as significant for the airplane pilot as for the driver of a car to shift gears in the transmission. This results in substantial savings in fuel, engine wear and noise.

Pilot controls the pitch through the toggle switch mounted in the cockpit. Pressing the toggle switch one way sends electric current through the graphite brushes to the slip rings and finally to the electric motor.

Depressing the toggle switch the other way-reverses the polarity of the current and the rotation of the electric motor. The pitch change operation is similar to the power windows in an automobile. As long as you hold the switch in one direction the pitch changes in that direction and you observe the result on your RPM meter. Torque from the electric motor is multiplied in a planetary gear drive which turns the lead screw.

Lead screw is supported by a thrust bearing and converts it's rotary motion into axial movement of the spool. The spool is linked to the supercams which turn the torsional rods. Torsional rods transmit the movement from the center of the prop to the outside section of the blade. This causes the blade to twist therefore changing the pitch in the same manner as the ground adjustable system.

Movement of the spool can be restricted each way by inserting washers on the lead screw. This limits maximum and minimum pitch and prevents engine over-revving.
 Can be adapted to other engines. Ground adjustable prop can be converted to the In flight Adjustable system by means of a retrofit kit. In-flight adjustable hub comes assembled with instructions on how to use it.
