Turn the wall 45* so that a vee is projecting into the slope?

I am not exactly sure what a "Mafia Block" is, but I have built many retaining walls with both Allen Block, and the large 2'x2'x4' blocks made from leftover concrete and sold by concrete companies, which I think is what you are referring to.

Well take your 2x2x4 and add a pair of shoes then drop it into the East river and you have your standard mafia block.
Mafia blocks are usually cast as 2x2x3 or 2x2x6 ft. The smaller blocks weigh around 1800lbs and the larger around 3600lbs. I dont know that you would necessary need a crane to place them. If you use the smaller blocks and have a decent size tractor, you could probably place them with the fel. Takes a large tractor for the larger blocks. If you lean the back course and backfill as you go up, you can also rise the outside runs on the same slope as you lean the back wall. this would allow for tight corners. It aint like you are going to be making 100ft runs so the slope on the side walls wouldnt be that noticable, unless you also plan on adding a roof at a later point. I am assuming the back wall is the 14ft wide, that is 3 of the 2x2x6 blocks wide and for the height, 4 or 5 high. For the 8ft side walls, you are only 2blocks long. Each end of the back wall will be supported by the side runs with only the center block being able to push out. I think you are over thinking this project, or I am looking at it wrong myself.
