Location of engine perches -- 360 vs. 300

[Drizzle]

Having searched high and low for this information, I have yet to find what I'm actually looking for. It's probably 'out there' somewhere, but if someone could point me toward it, i'd be very grateful.

I am swapping OUT a 360 FE engine and REPLACING it with a 300 cid inline-six.

How are the engine perches positioned for the 300 cid engine? I've found discussions and pictures showing the difference in the perches used for FE/300 vs. 302 and 351, etc. But as I understand it, the 300 uses the same perches the 360 did, BUT THEY ARE POSITIONED DIFFERENTLY.

Thank you in advance for helping me along my way...
