Cooling

A complete cooling system is more than just a Cheap rad. The rad is a big part, at the same time remember the more HP you make the more air fuel you burn, and the more heat the engine produces. The rad and the Fan are the biggest components for LOW SPEED COOLING. The more air you can pull through the rad the better. A good Water pump to flow at the correct speed, a good rad cap to maintain the correct pressure, and a good 180-195 Degree T stat to open and close to keep the water in the rad and the block. Anyone who runs a 160 stat is not doing their engine any good, that stat will never close, it just stays open and becomes a restriction to flow. I make 525 hp Aluminum heads intake and waterpump. I run a Smiths 22" rad with a shroud and 18" fan. A good aftermarket pump and impeller and a 180 T stat. I run 180-185 when moving, in traffic 190-195 and then drops back down once i start moving. 190-200 is NORMAL operating temp of an engine, it is not overheating. And you need heat in an engine especially if you have forged pistons. The rings and pistons need to expand so the rings can seat. Just my .02 but hey you asked.
