Quote: i ran a tall fill in a 360(414)for a long time @13.1comp brad penn or royal puple oil.tons of street driving and track passes no oil temp gauge ran super cool water temps never got over 180degrees.youll have no probs dont even sweat it.
Ever had the engine apart to see how the bottom end looked? Was your oil always clean and unburnt when you drained it?
oil was always fine mind you i changed it often 2-3times a season,never lost any oil pressure not even after crusing a while.i ended up selling it to a memeber still running strong in his demon.i think your probably even ok without it but if you do it half fill i wouldnt worry whatsoever.
