Here is what I would do-
1. Don't guess or ASSUME a cabane angle is correct.
2. Contact Doc Mosher and buy the W&B articles. Or borrow if you can't get him.
3. Do a weight and balance spreadsheet. If you don't know how, have someone help
you.
4. Download a copy of the FAA Weight and Balance Handbook. Google FAA-H-8083-1A.
It is free to download. Read it.
It doesn't matter if you lean 2 inches 4 inches or 6 inches if your gear placement
is wrong. That is key.

I'm in the final trim painting and assembly stage of my A-75-8 powered PIET. I
built as closely to the BPA wt/bal data by Wm.Wynn as I could and also used a
newsletter item that said BHP had recommended 3" aft sweep of the cabanes and
14" (firewall to crankcase) length engine mount for the small Continental. Per
Wm.Wynn, I also wanted solid welded diagonal cabane struts, so to make sure that
the wing position and engine mount length were correct, I bent 5/16" allthread
into a temporary engine mount held together by cable clamps. I made the allthreads
that protruded through the 4 crankcase lugs long enough that I could
move the engine fore and aft, and with the aircraft on the scales, played cabane
sweep versus engine mount length until I compromised at 17.5" C/G. Final position
is sweep 3-13/16" and engine mount 34" (using the same measurement locations
as Wm.Wynn stated in his articles). I haven't flown yet, but I'm dead
certain of my C/G. See attached photos.
