I was just wondering about my oil pressure. When cold at idle its bout 30 lbs but when full temp its down to 10psi at 600 rpms. Its a completly refurbished motor. Not a single part was left untouched in this 304. 8 quart Milodon oil pan too. I bought a pump housing and adapter plate all nickel coated from Bulltear. Im running 10W40 Valvoline with a mobil 1 filter. It just seems kinda low to me? Also what do y'all think of me running 15w40 Rotella T in this motor during the summer months? Planning on doing a remote filter setup and a oil cooler later on but what you guys opinions?
