I have a 3 row aftermarket original style radiator with my 428cj. I am running about 200-210 degrees and it hasn't even warmed up yet. Will a 4row help?
My 390 (same block as 428), bored .015 over, using orig stock '67 3 core radiator, new stock style 7 blade clutch fan, fan shroud, plain 50/50 anti freeze, using recomended 180 t-stat, correct radiator cap and mechanical temp gauge & aluminum Edlebrock hds. I spoke with my engine builder about temps and he said an FE engine should run around 210-212 degrees. He was right. I've driven this car down the highway with air temp @ 96 degrees couple years ago as well as sitting in traffic on hot days and mechanical temp gauge never goes over ~ 212 degrees. Make sure fan belt is snug.I have a 3 row aftermarket original style radiator with my 428cj. I am running about 200-210 degrees and it hasn't even warmed up yet. Will a 4row help?
I have a mechanical temp gauge. I also used a temp gun on the radiator and water neck housing. I am running a mechanical fan w/shroud. And yes, the fan is in the shroud where it is supposed to be. Timing is where it should be. I am running a 50/50 mix. I don't think I have a fuel problem or vacuum leaks but I will check again.
I have read some threads that mention taking a 3 row and making it a 4 row with a staggered core? Not sure if this would be different than getting a 4 row. My current 3row is leaking at the tank and I am sending it back this week. But, in the mean time I am trying to see if the 4 row will help. I don't really want to trick the car with water wetter.
The 4th row only gives about 10% increase in cooling, since it slows airflow, and of course the air hitting it is already heated by the first 3 rows. Shroud, thermal clutch fan, 190° thermostat, clean 3-row radiator, and functional distributor vacuum control valve are all things that will keep it cool.
This one runs cool:
It appears we have a smiliar set up. The only thing I can see different is my fan is a just a mechanical. Does this one run 200-210?
