70 Chevelle ss ls6 454 Harrison radiator

Somewhere along the way, before I rescued it, the radiator in this car disappeared. I'm trying to get it back to its original state, or as close as possible without completely breaking the bank. It is a 70 LS6 454 with m22 trans, 3:31 rear end, and no a/c (which should go without saying). I believe I need the Harrison BQ XJ IA 3 core radiator. Certainly a needle in a haystack, but are there any replicas out there? It seems there are a few four core versions, but the original in this car was definitely a three core.

Re: 70 Chevelle ss ls6 454 Harrison radiator

Keep an eye out on ebay.3 core was more common than 4.You can find the tank codes from time to time on used cores.,any rad shop can get you a core.The triangle slots in the mounting frame might not be there on the core but it will be close lookwise.Hope you have your fan shroud,they are hard to find also.

Tried to order from Heartbeat Camaro. After they took my payment, I got a call about a week later that it was on backorder. When I asked the last time they had them in stock, the guy told me it was 2011. I graciously asked for a refund.

Re: 70 Chevelle ss ls6 454 Harrison radiator

Not sure if you've found this yet [attached chart from chevellestuff.net], but it will help you confirm your research.

FWIW, I had searched for literally years for a "BE" 3-core rad with IA/XJ tanks. Early this year I finally hit on eBay with a unit needing recoring. I used Radiator Master in St Olaf, IA to do the recore work and I'm glad I did. They used a hi-efficiency 3-core that has the cooling ability of an old 4 core while maintaining the 3-core size. The massaged out dents and dings from the tanks and were even able to repair a few hairline cracks in the old tanks. I have yet to install/run the new rad, but it looks great!

Re: 70 Chevelle ss ls6 454 Harrison radiator

I bought a four core made in usa core from them 6 months ago.Used my original side tanks and date codes.Core was an exact match right to the triangle cut outs.Not sure if they have a 3 core though.

Re: 70 Chevelle ss ls6 454 Harrison radiator

There is a guy in upstate Michigan that restores Harrison rads and has for years. Bob???. Used to be a link for his service on the Alum a tech site but that is gone now as well. He may have what you need. There have been some threads about his Harrison service so a search might find his info.

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?

Thanks!

Life is not a journey to the grave with the intention of arriving safely in a pretty and well-preserved body, but rather to skid in broadside, thoroughly used up, totally worn out and loudly proclaiming: "WOW! WHAT A RIDE!!"

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!
