So, after installing my newly built 493 stroker, I was concerned at how hot it was running. Even in the cooler weather we've been seeing down here lately, coolant temps quickly soared north of 220 (180 stat...7 blade fan, not a clutch fan). I was only taking short shake down runs so I never ran it that hot for more than a couple minutes. The previous set up was a stock stroke/displacement 440 with a 26 inch radiator and no shroud. I behaved nicely on the street running at about 210. I had been running the straight 50/50 prestone pre-mix. After much searching, I found a shroud that fit the radiator, but had to do some trimming to it in order to clear power steering hoses. I also drained out about a gallon of the 50/50 mix and topped of with distilled water. After a long drive in stop and go traffic, temps stayed between 180 and 195. What a HUGE difference the shroud made!
