The prop flange face to firewall distance is 40
inches.  I don't recall
changing the thrust line from stock but if you can
send me the location
of any firewall attachment point relative to the
stock thrust line, I
can compare it with the fixture and tell you what
the thrust line is as
built.  I am guessing that it is stock.   Jerry

Jerry,

Thanks for the update. I recall at 40" we had extended
the firewall to flange distance by 2". At one point we
talked about a thrustline offset but stayed with stock
in the end. The engine mount and muffler are well put
together Jerry!

Don,

That W&B spreadsheet would be great if you could
forward to me. After talking with  Kent Passer about
CG (who wrote "speed with econonomy" for experimental
aircraft based on his Mustang II) we decided ourselves
to move the engine forward 2" and allow a little more
room on the firewall for adjusting CG (with
accessories/batteries etc as needed).

Mark bad news! The connector is wired backwards. Injectors always
on. No spark. I hope the computer is OK. Tracy is at an airshow
so I could not talk with him about it. He will be back Sunday night.
