big Blockne
So I am new the this forum, but i wanted to know if anyone here has ever had a problem with over heating a big block. I have a 74 454 big block that i can't seem to keep the engine cool. any ideas on what i can do?

RE: big Blockne
Welcome To CF.
What have you tried so far?
Is this a recent development?
1. thermostat, what temp?
2. hoses
3. waterpump, any leakage?
4. radiator, may need flushing, restricted air flow?
5. does system maintain water level?
Give me some answers, and I'll try to give you some.

RE: big Blockne
what is done to the enging with mods,what kind of radiator you got,waterpump, what kind of antifreeze you running,what thermostat is in the engine, ...oh ya welcome to the forum, i love big blocks.

RE: big Blockne
DO YOU HAVE THE AIR DAM UNDER THE RADIATOR? THE RADIATOR GETS COOL AIR FROM THERE,NOT THTOUGH THE GRILL.

RE: big Blockne
Actually, what the air dam does is create a vacuum, much in the same manner an airplane creates lift. The dam diverts air downward and the resulting downward flow creates a vacuum directly behind the dam. A vacuum results in air behind the radiator to be pulled towards the vacuum, hence a better cooling effort. [8D]
