408 oil pressure issues

Have a mechanical guage, had the issues with 10w40 and have had the issues with 10w30. Reassembled it with nylon bushings on both ends of the oil filter adapter fitting and will soon test drive it to see if I still am having the same issues once hot.
Right on! May be a big difference there! I'm running 2050 but I'm down here in Tampa Bay it gets pretty damn hot but I still run about 185 when warmed up it'll creep up a little bit at a red light but it drops back down. I've noticed the oil pressure drops a little bit when it gets up to operating temperature but not bad the main thing is to watch that gauge when you're giving it gas and to make sure the oil pressure is going up with the RPM. That and obviously too low of a pressure'd scare the snot out of me anyhow!
