Re: 70 Chevelle ss ls6 454 Harrison radiator
I just picked up an original Harrison for my 2 door wagon that I'd like to have recored. Can I ask what you paid to have yours done, including shipping?
The price to recore the rad (with the high efficiency 3 core vs 3 core with original cooling specs) with shipping back to me was roughly $650 ($590 coring + shipping). But don't forget that you need to get it to them first, and they'd prefer if you didn't hack it apart to make it fit for a cheaper shipping price.
I was EXTREMELY precise in what I wanted being as communicative as possible. I was told that these cores are readily available pre-fab (sans-tanks but including side panels) and they are the lion-share of the price. I even sent them the GM radiator specs I posted here from Chevelles.net to aid our discussion, and asked them to compare my rad with the specs with the new core for size. They suggested the more expensive high-efficiency core as a safety margin in case of future engine work being done, which I hadn't considered. It was about a $130 more expensive than the standard core, but very much worth the price/peace of mind in the long run. Appearance-wise, all the dimensions are the same, just more fin folds per inch per row. You'd be hard pressed to spot the difference.
I very much appreciate the work Chuck did. He massaged and repaired the old tanks, assembled the new core with tanks, than did a pressure test of the completed unit. During the test he found a number of small cracks in the very old and stressed tanks (possible freeze damage) and then disassembled everything to address/fix. Assembled again and re-pressure tested to assure the work was complete. Then he painted it.
Chuck and Judy are good people. Judy will be your contact to discuss the job with, and Chuck is ex-Navy. Small shop. Support mom and pop!
