It's a bit complicated. There were actually two standards: X3.9-1966 and X3.10-1966. Exactly contemporaneous; one is "USA Standard FORTRAN" and the other "USA Standard Basic FORTRAN"; the latter intended for smaller machines, so the list of features is reduced. Both were ANSI FORTRAN.

S/360 had compilers for both varieties. The 1410/7010 FORTRAN described in C28-0328-1 on first glance, appears to comply with ANSI Basic FORTRAN. Certainly more F66-like than, say, 7090 FORTRAN II or 1620 FORTRAN II. No "READ INPUT TAPE" nonsense, nor punching "B" in column 1 to get logical expressions.

Both the usual and the basic varieties of FORTRAN are mentioned here:

The surprising thing is how spare the ANSI document is: 36 pages, including appendices.

Compare to, say, F95...
