Overheating wowes that make no sense - help!!!

Hi guys. I have a 71 Duster with a 100 mile 440. it has a Mopar prule cam and 10:1 comp.·

It was overheating with the old clutch fan and 26" original radiator. So i diched the lot!

I now have a new 440 Source housing and pump, 182 degree thermostat, a brand new 26" aluminium radtiator with twin thermo fans set to come on at 185 degrees. It running 33 degrees timing. It also has a seperate transmission cooler.

It is overheating and i dont knbow why. At 50 mph @ 2000 rpm the temp climbs up to 205-210 and just keep going to 215 and boils. I have veaired my spped and RPM to see if it gets coller if i go slower or faster. It doesnt seem to matter.

I am at my wits end.... I am tired of looking at the car too scraed to drive it in case it overheats - which it always does. Today it did it and the temp outside was only 75 degress.

Any suggestions???????????????
