Radiator Question

[MMiller1050]

Hello, I bought a 1969 Chevrolet C-10 for restoration. But, right now I need to get it running reliable for a short time while I get another truck painted. Found out it has a 1979 350 engine in place of the 1969 original 350. Is automatic without air. Question is the original style radiators are quite different. 1969 is a little smaller core size but is 3 rows.....1979 little bit bigger core size but is only 2 rows. Measurements courtesy of LMC trucks. Plus, the 1979 does not fit very well in the truck. I want it to cool properly and fit the way it should. Can I go back to the 1969 style radiator with a 1979 350 engine. Engine is not anything special and not modified. Pretty standard plain corporate 350.

Thank you.

The 69 radiator will cool off the engine without any issues if it is clean and has a shroud. No real difference in the factory engines. Still a 350

Thank You for the info. I will be buying a new shroud....the previous owner hacked up the install on the shroud it had.

Besides the above good advice, also get an OEM-style 7-blade 18" fan on a heavy duty (finned face) fan clutch.
