I think there have been a number of different sizes used, I used and aluminum radiator that measures 19" x 26" x 3". It came with a top fill so I took it to our local high school and had the shop teacher cut the filler off and cap the whole. I then used the inline filler. I have a 347 engine and my car has never gotten over 185 in south louisiana heat. And I used a elec. fan from a Lincoln Mark8.
