A 235 has a side cover that is roughly half the size of a 216 side cover. While a 235 cover goes to about 2-3" below the sparkplugs, the 216 cover goes all the way down to the distributor.
I think that relying on 'factory documentation' can lead you astray sometimes!
I didn't believe a 3600 or 3800 came with a 235, but when I saw the information page, I started to question my knowledge. Oh well. Trust your gut I guess! Plus the documentation lists a 216 as having 92 hp. I think it should be 85 hp if my memory serves me correct.
