428SCJ coolant operating temp ?

[ERA Chas]

Yes, a 180 stat and ditch the OE pump. Get E'brock's aluminum pump and save 9 pounds with better flow velocity.
I did.

Mark Deluca The Edelbrock is a high flow water pump. You may have one if the pump is for a car with AC. If not who knows what you got. Temp for the motor. 160 is too cool and causes the thermostat to be open alot more than you want. You need the motor to also heat up the engine oil for it to work at it's best operating temp. A 180 thermo will let a little more heat into the motor and also works the other way by letting the coolant stay in the radiator longer to cool down more. The ture test would be a hot day in traffic and see what happens. Racing my motor goes to about 185 and the thermostat opens and the temp drops 20 degrees in a hurry, about 10-15 seconds on the gauge. After a 20-30 minutes of racing, the temp is right around 185-190 max. It depends on how hard I am driving the car and if I am in hi rpms all the time instead of shifting to a higher gear. I would start with the water pump first and see what change there is. Put he old stat back in too. Rick L. Ps every motor is different, and they each have their own happy spots, like temp, A/F ratio, Carb, Airtemp, etc. Living breathing thing.

Rick, I think you'll find the Ebok pump flows a little less than OEM, at least I was told that by several engine builders.. It all ties into reducing parasitic draw, which Ebok tries to do.

Undy Dave I pulled apart a stock water pump and the back cover on my Edelbrock. The Stock ford one has the same number of fins on the impellor but there was no plate to help move the flow along. This pump could have been a water pump without AC. The Bearing was bigger on the EDELbrock. I did clean up the casting on the ELEDbrock pump. Alot has to do with the CORRECT pulleys on the waterpump and crank shaft. I went with the march setup and that motor overheated everytime. I got a custom pulley from ASP with the correct size as stock ones. I have not had an over heating problem since. I am also running a larger thermostat than the FE one that is called for. Everybody gets different info again Rick L
