Import crushing 428 engine

[MuscleCarFanatic]

Granted the 360 is not a performance engine, however, a 360/390 truck block can be made into a 428. I was told that only a truck 360/390 block has thick enough walls to handle the boring.
And correct me if I'm wrong, but isn't the 460 a larger block than the 360/390/428?
I was under the impression that a 360/390/428 block would fit with out modification in a '67-'69 mustang. I have seen 390/428 powered mustangs around (mostly fastbacks)....
