    cooling puzzle
    « on: May 31, 2015 - 01:03:17 PM »
    440,   .040 over,  eddy heads, Lunati Hyd cam. Griffin aluminum radiator flushed, new standard water pump, hi flow 160° thermostat. ( tried 180° standard too).
    Even on a 70° day it runs up to 225° at cruising speed. I tried cooling additive, new cap, new electric fan w/ shroud,  and I have a Milodon hi-flow pump ready to install. I'm baffled boys! So if you've dealt with this please comment. Thanks.

    Update... I put a laser temp gun on the sensor on top of the water pump. It read 195° but the guage read 212°.  So I think we have a problem with the guage setup. Its an AutoMeter mechanical. Suggestions?
