Just curious as to what radiator the 57 Ford Fairlane/300 crowd is running when you swap up to a 429/460? I have no clue what ours came out of other than it is FoMoCo and was made in November of 1976. My neighbor has a 74 F100 with a 302 and it looks really similar to it. What is a common swap radiator donor? Maybe a Torino? Ours seems to like to develop a new leak every time we drive it more than a few miles. Also, thoughts on Bars Leaks? Good, bad , ugly?
