First off , you should have a 17 1/2"x22"x1 3/4" radiator . If that is the case , Classic Industries has a shroud for that rad . Secondly , make sure the rest of your cooling system is up to the task . thoroughly clean the block and heater core . The shroud should do the trick . If it doesn't , install a clutch fan . You shouldn't have an issue after that . But just in case , you can go with a 160*F thermostat if it still runs hot . Make sure you have 50/50 coolant and DISTILLED water . When and if it's still hot let us know again and we will solve your issue . Good luck , Tom
