Radiator cap pressure

["Frank Marrone" <itswonderful@comcast.net>]

Anybody out there running 16PSI radiator cap?  I had my heater core modified
to include stiffeners on the end caps to help prevent the end caps from
bulging out but I did not wedge blocks to support the end caps or use the
big hose clamp method.  I personally pressure tested the core to 20PSI.  My
intent is to run the 16PSI cap and I'm curious to see what others are doing.
