Radiator/core support question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

77c10 · 06-13-2014, 09:18 AM

I hav a 77 C-10 with a 82 core support and front sheet metal. Until recently it had an LT1 from a Camaro in it and I used the Camaro radiator. I got rid of that motor and went with a 1st gen 350.

My question is, does the radiator set directly on the core support on the rubber pads? I tried it last night and the radiator was about two to three inches too short to reach the mounting brackets at the top. The radiator I bought was a Spectra CU730 which shows to be 28.35" tall. I'm not sure if there is a taller radiator made or not. I got the one that it called for from Auto Zone.

Sorry if this is hard to follow, I will take some pictures tonight to better illustrate what I am talking about if needed.

Thanks,
Tim

when I needed a new radiator the new aluminum core rads were a different size. I had to go with a different shroud and mount for it... the lower ones were movable and I got some kind of bracket off a newer truck... its been a while I forget how it went in

It is not 28" tall. Maybe 28" wide, but not tall.

Now that I think about it, you are right. Auto Zone has it listed backwards on their website.

I saw a truck in the salvage yard the other day with extruded aluminum risers to mount the rubber isolators in. They were about 2" tall or so. They looked factory, they were riveted in too. I had never seen anything like this before V6 maybe?
