388 Cooling Problems
Hey- I had a 383 stroker (.30 over) and i blew it up, so i went .60 over on my new engine making it a 388 stroker(the block is a 81 4 bolt main). I have a 165 degree thermostat and my timing is set correctly. I am using the stock electric fan which runs constantly and a aftermarket 2 core jegs radiator, and a stock water pump. I am playing hell trying to keep this engine cool, with my old 383 i would run around 190 to 200 degrees with this new 388 i am running 240-260 when driving and about 210 at idle. Anyone have any ideas how i could keep it cooler?

Larger radiator (more area to reject the heat);
Greater coolant flow and air flow (to make the radiator more efficient);
Less generated heat (correct mixture, less loading, etc.).
You may have reached the limits of cooling for the size radiator you are using. Increasing cubic inches in the same size case (same volume of coolant) means that the coolant is going to gain more heat energy from the engine, and then will need to reject the added heat energy at the radiator. If the radiator isn't adequately sized to reject the additional heat, you may not have a solution.
