Yes it will. Believe it or not, when the Mustang was redesigned in the early 1970's, one of the key things that Ford wanted was for the 429/460 to bolt right in.

The 429/460 engine family has a better than average production oiling system. Very little needs to be done to it to sustain 6500 rpm, occassional 7000 rpm bursts, specifically meaning the design & layout of the oiling galleries and their internal (volumetric) dimensions are far greater than the passenger car 460 engine really needs. The stock rods, however, are questionable...some people luck out and others experience disaster under the mildest circumstances. They are the weakest link in the motor, certainly NOT the oiling system.

In regards to the scar in the bore, as long as it is smoothed out AND does not go high enough in the bore to where the piston rings will cross over it at bottom dead center, you may be okay with your mild build. But if the piston rings pass over the scar, then you may need to rebore or sleeve.
