460 engine perches

[M-100]

I'm going to install a 460 in a truck that is supposed to have had a 390 but currently has a Chevy 350. I have the factory 460 perches and mounts will the perches bolt in the same holes in the frame or will I have to drill new ones. Nothing against Chevy motors but they need to stay in chevys

Here is a technical article that talks about engine perches, it does mention the 460 engine, not sure if this helps, but here it is:
