360 Core Questions

I found a 86' 360 in the local junk yard for $300.00 Dollars. Supposedly has about 40,000 miles on her, but am planning to rebuilt it. Like the advise I've read here about E-Brok heads and such. So I guess my questions go like this....

Are there any differences between the early 70's and last 80's 360 engines?.

Are the mounts the same, or does it take a different mount based on year?

Do they bolt into the frame the same way?

The project Car I'm planning to put the engine into (68' Dart) obviously doesn't have EFI, and I don't have Electronic fuel injection or a computer in the car now (currently a slant 6 - 225), what would you recommend?

* Pull the current manifold and get a Carb and Manifold?

* Are there any aftermarket EFI kits you can install on an older non-computer car (like the 68 Dart)?

I'd like to learn from the experience here on the forum. Thank you for all the help.
