I had a 63 1/2 Galaxie I built in High school. Dailey driver 427 top oiler 2X4 C-6 411 gear. No over heating problem then anded a
oil cooler with the
oil cooler never went over 180degrees even at a traffic light. I live in DC area. Had lots of big block ford freinds at the time. Driven 428 Mustangs and have to say I was not impressed with the 428 compared to my 427 and was in a car 1000 pounds heavier. I love 427!!!!!
