hey guys i have an over heating problem and cant figure out what the cause is. its not a problem when driving but when i am at idle. i have a stock 350 crate engine from jegs. i just installed a dual core radiator that should be sufficent cooling for this engine. i also have an electric fan that kicks on at 190 which hangs around there than shots up to 210-215 after a few min. iv had a complete tune up and does anyone know what i should have my timing set at?? Can anyone help i wanted to take this car on a 400 mile trip im goin on next week and as of right now it seems to not be happening.
