Block Adapter, Big Block Chevy Gen 5 & 6 Thermostatically Controlled Engine

Maintaining proper engine oil temperature has become critical to the success or failure of today’s performance marine engines. Prolonged use of marine engines in conditions where oil cannot reach its optimum working temperatures will result in sludge formation and crankcase dilution which leads to excessive wear especially in the cylinder bores and bearing surfaces. A thermostat assembly combats this by permitting 90% of the engines oil to bypass the cooler during warm up. The balance of the oil flow is allowed to fl ow through the cooler maintaining constant pressure and preventing air pockets while eliminating cold oil shock. This reduces scuffing and premature wear and inhibits engine blow-by. As engine oil temperature reaches its optimum operating temperature moisture and impurities that often cause a milky condition are eliminated. Until now oil temp was controlled either by some guess of components or by the professional engine builders through the use of some sort of external en
