470 Rocker Ratio

Send Mydixiewrecked a PM... I asked some questions about my 0-470-R, and he posted up with PDF files from factory books.... He may be busy and did not read the thread....... He is a wealth of knowledge with aircraft motors..........
 
You can figure it out by measuring from center of rocker shaft to each end to,push rod fit and valve contact tip. General idea.
 
Lycomings are 1:5:1. and O-200 TCM are 1:2:1, so an O-470 should be somewhere around these? Not that I was much help to your question!
