Nuttyprofessorr's own 727

Although this 727 is on a small block engine, it has been extensively modified to learn and make it almost bullet proof, and last for a long time.

It has been modified to a lock up converter, which involves changing the input shaft, the pump assembly, and the valve body. Naturally the converter has to be changed as well.

Various billet parts have been used to further improve the strength and ultimately the reliability.

To further improve the reliability the gear train has been improved with 4 gear planetary gear sets. The usual gear sets have only 3 gear sets. The 4 gear sets are usually only found in HD 727’s on 440 magnum engines and 426 Hemi’s.
