Do any of you know who holds the STC for the conversion of the Pawnee from 150 to 180 HP? Information would be greatly appreciated. Bob

Getting a field approval these days would be nearly impossible. From what I have been able to gather there was a STC on that conversion. I have a 150
Pawnee that I would like to convert to 180. I thought that the Jeff Cloud Pawnee was done through a STC not a field approval.
