I think it would work, the plates are only about an inch tall and you will move that tall part of the mount back with it.

I have the same 4.3 engine in my 41 moved back 10 inches, albeit without the relocation plates, but that part of the mount that is sticking up gets removed and moved back on the plate. I wish I could show you a picture but photobucket, which was made specifically for 3rd party image hosting, just put the kybosh on 3rd party hosting unless you pay them. so I am shopping image hosts, and I suspect there will be a lot of people doing the same.
