Hello! I know this topic has been discussed ad nausem but one more question, please. Car is 1967 400/335. Engine just fully rebuilt. Car ran hot before rebuild. Runs hot after rebuild. New 4 aluminum radiator. New EFI. New high volume water pump. Timing seems to be set optimally. Water wetter. Now that temps are getting warmer, runs hotter. At 55, temp around 210...but stopped at light or stop and go traffic, temp shoots up immediately to 230 or so....perhaps more but I haven't put myself in a position where it could. Electric fans didn't help. Tried various thermostats, didn't help. So, desperation. Has anyone tried waterless coolant like Evans? Any meaningful results? As always, thank you.
