Hey engine gurus.
I can't seem to find the valve lift data in my SSP1776 table of limits. Can anyone supply me with lift at the valve (intake and exhaust) on an IO360 A1B6 angle valve? I am also interested in parallel valve data.
I am building a flow bench and am interested in anyones experience porting the Lycoming cylinders. Particularly flows at 28" differential before and after porting.
The intake ports have a nasty sharp corner on the small radius of the intake port. I realize there is not much that can be done with the port, but how much difference is gained by smoothing the sharp corner?
