hi, my 67 gto sits on 190 driving but as soon as i sit and idle the temp goes up, today in traffic temp went to 215 before i got moving again, if i had to wait longer it would keep going up etc, i have had the water pump modified to flow better, also installed a new pully to spin pump faster, installed aluminium manifold which should help cooling, installed a coolant recovery tank, and just replaced fan clutch with the hayden severe duty, when i bought car receipts show the harrison rad has been recored with a max flow core , i could install a aluminium rad but thinking that may not change anything as my rad looks fine, i have a hi flow 180 thermostat installed, i thought about electric fans but many seem against this idea so what can i do, any ideas? thanks
