What is wrong with my motor? Figure this one out!!

If there was a contact issue when turning the engine over it should have been detected, it would of had a very hard spot of just stopped. I would ask the builder about what plugs were used behind timing chain, and if there is a oiling hole used and if so what size. the cam bearings can be a problem if not correctly installed, I ran into a problem similar to this years ago and found I went to a straight 30 wt oil when breaking it in, I had 3 or so lifters not pumping up. I found the problem and so I went to my parts room grabbed another set of lifters and took them apart, I found they had been packed with cosmoline and I figured they were plugging things up, I drained the oil put some 10wt in it re primed it like crazy with the valve covers off untill I saw oil out of every push rod I then drained the oil, put some fresh straight 30wt in with a new filter and fired it up after about 40 seconds it was all fine. That is the only time I have ever experienced a problem like this, not sure it its your problem but a area to look into. Also what kind of oil pressure are you seeing? Good Luck!!
