I was wondering if there might be holes on the outer edges that I couldn't see.  So there are 2/3 more holes than can be seen in the pictures.  Obviously, there's enough flow to do the job.  Also, I noticed on the second picture there appears to be a hole or two that appear to be plugged.  I would surely want to be certain that my system is thoroughly flushed when using a/c cores (especially used ones) so as to prevent blockage of these small holes.

Fellows: I know I don't know what I am talking about; so, if this is a waste of your time, I apologize. Many years ago, when I was a porsche man and a good friend was attempting to convince me that the mazda rotary engine was a better, much cheaper way to go sports care racing. He was having oil temp problems. Local stock car fellows, for whom he built/balanced engines, were using gm evaporators (not condensors.) We looked at several and found some had much larger cooling tubes that worked better with heavier oil that large clearance american engine stock car engines needed than others. Since we were working our way through local man-malls (junkyards, for those not familiar with the phrase) those we could/couldn't find were not costing much, it anything. I don't remember what we found to be the best; but, I do know we wound up stringing a couple together to produce great cooling results. I think they were mid 50s to later cadilacs, buicks, big gm stuff, just not sure. Ya'll might want to look into that aspect. Look at old junk and compare, see what/if there are any differences anymore and tell the rest of us. <g>
