Don't know if anyone else has faced this problem.  I just finished the rebuild on my 312 with a brand new isky cam.  I was really worried about a dry start and made sure I loaded the cam with their moly lube and also lubed the cam journals with the high pressure moly lube.  After start up had no oil coming to the rockers.  Pulled the motor to look at the completlely wiped out bearing 2, 3 and 4 for the cam.  My machinist talked to comp cams guys and they said you can't use the high pressure moly lube on babbit bearings and they suspect it blocked the oil holes.  So started over.  My rebuild is almost done and I'll pt it back in in the next coulpe of weeks.  Did spin up the oil pump today and I am getting plenty of oil up there now.  Wish me luck.  Always a little stressful dropping the engine plus long tailshaft super t-10 into an old t'bird.  Posted this because I had never heard of this problem before.  MIKE

Mike, still lovin his 57 t'bird after 53 years!
