In late 2020 I pulled the stock 301 out of my 1980 TA and replaced it with a Butler 461. The 301 had a small two core radiator, I replaced it with a cold Cold Case radiator and couldn’t be happier. I have a 180 degree thermostat and my EFI displays has never gone over 185, even in heavy slow moving traffic. I am running the stock 301 fan, clutch and shroud. I should mention I have not charged my AC yet, that will be the real test.
