Engine won't cool off!!

Hello - I have gotten to the point of getting my 318 to fire up relatively easy. Eveyrhing seems to be working well however the temperature always gets hot after about 10 minutes of running. I have taken the thermostat out, and she'll come back down to about 3/4 of the way and hover back and forth. My combination is a 318 with at Weiand Stealth 8022 intake. Does anyone have any ideas on how to cool it down? Thanks in advance!!
