according to the advance auto parts websie, they are, but the do not list a 390 in a 67 f100 so I went up to a 1970 model on both motors and they both listed the same part number

Ran into a inlet / outlet size difference on a 1974 F100 with a FE 360 many years ago.
The Advance part numbers said it was the same, but found no info on the inlet / outlet size. Only core width size and number of cores.
A small block Ford those years had, if I'm not mistaken, 1 1/2" inlet (top) and 1 3/4" outlet (bottom).
The FE Big Blocks had 1 3/4" inlet (top) and 2" outlet (bottom).
Check the measurement of the inlet and outlet on the water pump and engine block or you may end up at the radiator shop like I did, a brand new radiator with the wrong sized inlet / outlets.
They suggested that I run a custom 1 3/4" to 2" hose and 1 1/2" to 1 3/4" hose but from what I know about flow thru a certain sized opening, you won't get as much cooling with those size restrictions from a small block radiator on a big block engine.
The old radiator had the matched inlet / outlet sizing.
Wish I had known LMC Truck back in the mid 1990's. I believe they have the proper radiator for a FE application. Call and ask about the inlet / outlet sizing.
