Official NBS 4.3v6 to GEN 3 V8 swap Guide

Ok so my friend completely removed my vats from my computer (i still have a aftermarket alarm with starter kill) and it started right up and sounded mean but i had to shut it right off again because there is NO oil pressure and the valves are clacky as hell. I am going to pull the motor and check the oil pickup tube o-ring. I am pretty sure the stupid kid i bought the motor from messed it up when he had it taken apart. If this doesn't solve my problem i am going to save a couple of weeks and put in a 6.0 because i really don't feel like messing around with a stupid oil pump because i have read it is not so simple.

if youre going to pull the motor again you might as well just put in a brand new and bigger aftermarket oil pump to be safe. Its not that difficult if the motor is already out of the vehicle and it should only run you about 200 bucks depending where you shop around at. The oil pickup tubes are notorious for causing low oil pressure in these motors though. You will need to make sure that the tube and o-ring are seated correctly in the hole and that the tube is not the cause of your problem first.
