Oil slosh
I lost two engines, like that but at high rpm. It ain't happening again,lol.
7qt pan, calibrated dipstick, hi-volume pump, modified drainbacks and modified oil delivery passages. I'm good to 7200 at least,now.
Factory gauges now; I never look at em anymore. Except the speedo; I'm not interested in getting any speeding ticket. The tach now, that one I have to watch practically all the time; it has a nasty habit of scooting into the redzone,all too often.lol.
