I dont know the oem number but I think you would have good results with one from autozone. I bought one about five years ago and have been happy with it. A competent chevy dealer should be able to figure it out without a vin.

Re: OEM Radiator # for 350???

When I bought my Camaro in 1984 it would overheat every now and then so I checked Chev service bulletins and found this bulletin.
Bulletin # = 84-154
Section 6B(XIII)
Date June 1994

New radiator assembly #3047198
New lower air deflector #14079836

I had the radiator and deflector installed under warrenty. The car was ok after that. The radiator (three row) and deflector looked the same as the takeoff parts but must of been made of differant materials. I have since then installed a 355 and it will only overheat when it is 90*F and using the A/C stuck in traffic. If I turn off the A/C it cools down pretty quick. I run a 160* stat with (4) 3/16" holes drilled in the stat. Only good for summer.

current, 52497687 (gmpartsdirect or, newgmparts)

There was only one radiator for the v8.
Only the 2.8 v6 had a different radiator from any of the other engines in these cars (if I recall correctly).
