Here is one data point for Tom Giddings taken 2/8/99 for a wrapped exhaust
system with Vision EGT probes as close to the exhaust flanges as possible.
Sorry it is not a 360 but a 235L2C.
All cylinders close to the same with 1550F EGT average for 70% power at 6500
feet MSL, 65F OAT. (Eat your heart out, this is Arizona) . (2725rpm, 20.5
inhg manifold pressure, 6.2 GPH fuel flow, with 60X74 Demuth fixed pitch
prop, 161mph CAS, leaned to rich side of peak EGT)


For Jim Solensky.  After 2 years my 235 developed an oozing fuel leak at the
inboard end of the right wing.  Nothing to do but pull the wing. The leak
was around the gasket of the tank access panel I had put in the outboard
wing BL50 rib.  It was a BUNA rubber gasket fastened with 12 #6 screws
sealed with permatex #2.  I resealed it  the same way.  I now have 2 years
on the new gasket with no leaks.  The left side has never leaked.
