318 to 340 swap

There always seems to be discussion about this. All I remember is, when I put a 340 into my '70 RR body years ago (318 was only SB offered in B bodies then) I used 318 engine brackets and 4? washers under one bolt.

When I went from 360 to 340 to 318 in my old FJ -40 Landcruiser, I used the same engine brackets that came on the 360--were out of a 74 Dodge pu. I don't remember any important issue between the engines.
