Engine gets hot at idle

If you have a stock 350 engine a 2 core radiator should be enough. The last time I checked you can get one online (or locally) for about $120-$140. I gave up on having radiators rebuilt because new ones are relatively inexpensive. Also, you might get $35-$45 for your old radiator core (you should separate the brass/copper parts from any steel framework prior to taking it to the scrap yard.)
