Synthetic Oil in 76
Ok guys I have a 76 K15 with a 350 motor with maybe 3500 miles on a rebuild. I want to go full synthetic. I have Mobil 1 5W40 in it now. Im thinking of going Royal purple in everything, motor, 4spd, transfer case, front and rear ends.
Which one you recomend and what weight would be great, I know I need 90 weight or so gear oil but what about the motor
