Bear in mind that while the 360 is "almost" a bolt in, there are two important differences:

ONE: Your 318 pan won't fit, so I hope you have a new pan

TWO This is most important!! 360 engines are externally balanced, and need the proper front balancer as well as a special flywheel--in the case of a stick. for auto's I'm not sure whether the drive plate is weighted or the converter, be SURE to check this out. Any good transmission shop will know this.

DO NOT run a 360 without taking care of this. Not only will the engine shake badly at some RPM's, but you might just break a crank!!

I don't remember about the mounts. I do remember vaguely that when I put the 340 in my old '70, and used mostly 318 hardware---then, there WAS NO factory 340 in a B body---

seems to me I reversed the 318 motor brackets from pass. to drivers side, but I don't remember for sure. I also remember vaguely that I shimmed one bolt (drivers?) on the engine mount bracket.

Generally, you want small block brackets and mounts that go with the BODY that you are using.

I would think that the '74 brackets and mounts would fit.
