Make sure you didn't wipe a bearing, if the pump wasn't working for any amount of time, it might have done some damage. As for the oil pressure a stock 350 will run 15-20 lbs at idle and up to about 40psi under higher RPM's and a bandaid for lower oil pressure is thicker oil, 20w50 or straight 50 if in the warmer months. The 4X 4 lo or 4hi will make a different feel wheather the 4X works or not as 4lo still makes the rear 4 lo, so you should notice high RPM and slow moving in 1st gear. To check the 4X4 you need to be sure the hubs lock and that is it, the transfer case is gear driven, so once in 4X the front axle will turn unless the transfer case makes loud noises!
