With a car that old, who knows what has been swapped out. Pic might help identify it.
I am by far not an expert only having a bird for a short time, but I've read about an interceptor special engine 352 for 1960. Details vary on the source, but seems it came with solid lifters,
holley carb, dual point distributor, aluminum intake and different exhaust manifolds. I can only find one supposed pic of this engine online but it appears to have a distributor without a vacuum advance. Not the right year for yours but again things get swapped out.
