Another engine temp question. I've got a 272, pertronix with a flamethrower coil, plugs at .045, holley 465 on a 57 intake, dual exhaust, RV cam, .030 over, large valves in heads and Fordomatic tranny. I've been running around 190 all the time, thats with the heater valve open on the intake, if I close that off its over 200. I fabricated a test shroud and it didn't make any difference so apparently I'm moving maximum air thru the radiator, the little bit of extra air thru the heater core keeps it around 190. I put in a NAPA #6 stat but now I'm out of tricks and with hotter weather approaching I'm getting a little concerned. Is there a different radiator I can run, wagon, truck......whatever that has more surface area or core depth that will help? My wifes feet are getting extremely hot with the heater on sooooooo, gotta come up with something. Gary
