Dartin for Divorce

I would give it a good flush as 66fyssh suggested. Put the shroud on once you get it. My son's 360 has been built up( internal work is unknown , but very lumpy cam, 175 psi/cylinder, 190degree thermostat,homemade aluminum shroud, stock radiator with an over flow jug attached and it runs 195 to 210 degrees in our 95° plus humidity summer weather. Maybe give the rad a try with your new mods to save a couple bucks?20181111_161643.jpg
