Paul Lamar What is difference in CG position compared to an O320 (ballpark estimate)? I plan on

mounting as close to the firewall as I can get and still leave room for accessories and
maintenance access. This is both to avoid the prop strike in my LongEZ, and to allow me to move
the battery weight from the nose to the back.

I think I will let others answer that question as it seems to vary
from installation to installation. Perry's set up is real heavy as he
is using a real flywheel, cast iron exhaust manifold and stock
intake manifold.
