Radiator Replacement Suggestion

[jsburton69]

I need a suggestion from you pro's. I have a 67 GMC with a mid 80's 350. I want to replace the radiator due to cooling issues and the inlet and outlet are too small for a good hose fit to the block. I want a 4 row due to running with AC and an automaic T350. Was looking to purchase from Autozone put can't find a good fit because the only engine for a 67 is V6.

Just measure your radiator size, then get a four core.

The same size radiator will fit 67-72.

Just tell them you have a big block with A/C and auto trans. Tell'em you plan on towing an aircraft carrier.

Try Advance Discount Auto. I bought a 4 row for my pickum-up truck from them a few week ago. '70 with a 350 4BBL. Part number for that radiator is#43-3369.

I agree....why buy anything else, go for the big one!

Modine part# 433369 or 369, depending on part numbering system used. Just tell them to interchange that number or PM me.

If you do not have the thick mounts, you then have the 2-3/4" mount then use:

Edit...
from one of my earlier posts:
If you need to know what you have or need. Here's some helpful info.
Measure the depth (front to back) of the radiator area that fits into the saddle. It is either 2-3/4" or 3-1/2"(this is the area where the tanl is soldered to the core) you'll also need to verify which saddles you have... measure the indention in the rubble pieces in the saddles/mounts. they should be approximately the same measurements as above, either 2-3/4 or 3-1/2".
The radiator for an A/C truck is no different than non A/C, other than an A/C radiator is always a 4-row, that requires 4-row saddles (bottom) and 4-row hold-downs (top) they are the 3-1/2" long at the rubber mount, as opposed to 2-3/4" of the 2 & 3 row radiators. Although you can run this 4-row Radiator anytime extra cooling is needed (Big Block & any A/C truck had the same 4-row radiator stock.)
The only other variation from this is the 6-cyl radiator, it's narrower. Only about 26-3/8" wide, measuring only the core width, it's a 2-row core.
All V-8's, whether its a 2-row, 3-row, or a 4-row are all 28-3/8" core width. But, if your going from a 6-cyl to a V-8, you just need to relocate your saddles and top mounts on the driver side out to the next set of holes on the radiator support. and use a 28-3/8" core width radiator. Either a 2,3, or 4-row of your choice.
Also, if stepping up to the 4 row radiator, the upper & lower saddle mounts & rubbers are available. Either from one of the board vendors of still from GM (about $80-$100 from GM) You'll need 2 lower cups/brackets, 2 top brackets & 4 rubber isolators.

So, in short form:
6 cyl non A/C
had 26-3/8" wide core with 2-3/4" thick saddle mount
V-8 with 2 or 3 row core V-8 non-A/C & some 6 cyl
had 28-3/8" wide core with 2-3/4" thick saddle mount
V-8 with 4 row core Big Block or V-8 with A/C
had 28-3/8" wide core with 3-1/2" thick saddle mount

Hope all this helps... If not call me 605-381-5430 (I worked at a radiator shop for quite awhile)
