Freestanding Block wall

I'm building a wall to hide trash cans. Poured footing is in, 36" deep x 72' long x 16" wide. I plan to lay 4 (8x8x16) blocks long, 64". How high can I safely go? How many blocks high? I'd like to go 8 blocks, 64", with a cap. What do you think?

8 blocks high is really high, over 5'. Would you need that height just to hide a trash can? I don't think you would have a problem, but I also would drill 3/4" holes in my footing and epoxy in a few strategically placed rebars vertically so they fall in the holes of the block (probably 2 on the end and one in the middle) and fill those cavities with concrete.

You mean your footing is 72" long, right? Are there rebars in it? It should have had horizontal rebars and then vertical rebars up from the footing tied to the horizontal rebar in the footing to put the block over. 4 would be sufficient, then a horizontal rebar on top under your cap also tied to the verticals. 1.5 rows of block should be below grade also.
