Polished Stainless Thermostat Kit For Chevy, 455 Olds
This thermostat kit fits small and big block Chevy, 455 Olds. We found the majority of marine engines run far to cold to obtain proper combustion temperature. This results in lower power output, economy and engine life. Most engines are designed to run at a minimum water temperature of 160 degrees to achieve peak performance. This thermostat system is designed for use on cold water source cooling systems. It will keep the engine temperature between 160 and 190 degrees which is the most desirable range. The temperature will cycle up to 30 degrees within this range, due to cold water entering the system when the thermostat opens. We do not recommend this system be used on supercharged or turbocharged engines which run for long periods of time at maximum or near maximum power output. We do not recommend this system be used in extremely sandy areas - sand build up can interfere with proper operation of the thermostat.
