I’ve got a 440 in a 71 Duster, 26” ECP radiator using the Ford Contour fans and shroud. I did have to take a little off of the shroud to clear the pump. I don’t have any road time as of yet but I did break in the cam with this set up and never saw any more than 210* on the gauges. That was 2000rpm for 30 minutes in 95* California summer afternoon in the garage. Just some info to chew on.
