No that seems a little high to me I have 2 of these both supervans with 240 I-6s in them running original radiators and they run just alittle above center on the temp gauge and i drive my 66 daily. you might wanna have the coolant system flushed and also add a couple of 12v fans to push cool air up into the engine box from the bottom of the rad up and make sure you have the belly pan installed - just my 2 cents have a great day robert
