I think you need a higher temp thermostat. The 160 is open all the time, allowing maximum flow- but does not keep the coolant in the radiator to sufficiently cool it. The thermostat is designed to open and close to regulate the temp- not just open at a certain temp.







I agree Kirby, 180 Thermostat probally would be his best selection, that's what I run in my Daytona, and usually recommend that for most wingcars running a stock set-up, to up under 500 HP.....but the OP needs to confirm some items in the cooling system, engine timing, even perhaps carb jetting, and/or air/fuel ratio,.....but one can only assume what/how the OP has/is diagnoising his problems,....we're all armchair quaterbacks because there's little info to go on,..
