140/160 change over

[tony la rotta]

1. I have some questions about this 140/160 stc.
   
   So I see some people changing the cylinders to accommodate bigger cylinders and get the extra HP. The other ways I see is installing the powerflow exhaust to get it also.
   
   How much payload increase is any of these changes give? Also I see some 140 body aircraft with the 180 engines, is this a possibility also?
   
   Thanks for the info.
