Yes, conversion of FORTRAN-IV to Fortran-77 should be easy.
And considering that many systems ADD capoabilities, converting
Fortran-77 to FORTRAN-IV might be a bit harder.
If the FORTRAN IV program conformed to the ANSI 66 specification, no
conversion should be needed. Certain F66 features may have been
deprecated, but they would still compile correctly on F77.
No, try a vendor-specific FORTRAN II, say, 7090 FORTRAN with all of its
"interesting" additions, just as Column 1 punches for complex and
boolean arithmetic.
Better yet, convert it to, say, F90.
