NV3500 in my 74 Duster?

I am beginig a total restomod on my 74 Duster.
I read somewhere along the way that an NV3500 is a good economical manual trans to put in an a-body.
Can anyone share any experience with this kind of swap?
My Car is a factory 318/904/8.25
I was going to freshen a 360 for the car but im now considering a buying a mild build 318 and rebuilding the car as a twister.........
