Im having a problem with my dads 440. We are using a 26" champion alum rad, new thermal clutch on 7 blade MP fan. Flushed the block. goes to 215 on the high way. Gets so hot that the fuel boils and car cuts in and out.
I have a 440 source pump and housing on it... Doesnt puke coolant but just runs super hot!
We took the clutch fan off today and put an HHR elec fan and shroud on and its still 200 degrees on a cool 70 degree night
