Farther back in the pages of this forum I had posted a few pictures of a Brison 3.2 installation. I believe they are still there. Unfortunately, I can't post new ones due to my current location. The 3.2 will fit inside the cowl with the exception of the top of the cylinder head. The muffler relief needed will be close to, or the same as, that needed for a DA50. Easy engine installation overall.
