Will a 17" w/6 Blades, Standard rotation Fan work on my stock 350 engine I'm having to replace the fan?
its just a stock 350 L48 no mods it has a shroud on ityouve asked a question without providing a 10th of the related useful info
first the fan has a CFM (CUBIC FEET PER MINUTE) (2500 cfm and up is generally a decent start point for a performance engine,and an AMP rating (ELECTRICAL CURRENT requirement ) generally this falls in the 40-50 amp range (peak draw)on a performance engine with a single electric fan which your cars electrical system may or may not be able to fully supply, if the alternator is not able to fully supply the fan motor electrical draw, it will not provide the required air flow.
fans generally require a matching fan shroud placed and correctly clearanced on the rear of the radiator to reach the full cooling efficiency, your radiator will generally require about 1.4 square inches of surface area per cubic inch of displacement. your engines water pump must be able to provide the required coolant flow and the t-stat must also not restrict coolant flow rates.
ignition timing effects the engine combustion and exhaust gas temperatures, so thats important.
keep in mind almost all the engines heat is generated in the upper 2" odf the cylinders, combustion chamber and by heat generated in the valve train and rotating assembly, thus OIL FLOW rates are also critical as its OIL flowing over the engines moving components that absorbs and transfers at least 70% of the engines higher temps to the block and coolant, thus adding an oil cooler with a fan to also transfer heat absorbed by that mass of oil will further reduce the heat load on the engine coolant!
with an auto transmission, the heat load the radiator deals with is further compromised by the transmission fluid heat transfer, so adding a trans fluid cooler with an auxiliary fan will again reduce the engines cooling system heat loads.
You'll be fine.its just a stock 350 L48 no mods it has a shroud on it
Electric fans will outperform mechanical fans at idle. All day, every day. No comparison. Because overheating is 90% about idle time.
