Thought I should wrap this up and let you know what happened with this, thanks again for all the replies. We got the system working right last week-end. Basing our actions on the idea that there was a restriction in the system, we removed the refrigerant, then flushed the condensor and evaporator and made sure the hoses were clear. We then vacuumed it for over an hour at 28+ inches and checked to make sure it would hold the vacuum. Then we slowly applied the refrigerant, this system has always been R134, was never R12. We did not have a scale to measure how much we applied. The pressures came in just like they should and we ended up with just under 30 on the low side and 190-200 on the high side. We had to set a fan up to blow through the condensor to get the final pressures just right. It is blowing 35-36 degrees with the fan on high now. The odd noises are gone and it seems to be working like it should. We believe there may have been residual oil and/or dye in the system and flushing it has solved the problem. So Stu Cool (that's the Studebaker's name) is indeed cool as it should be!
