Scott,

 

An aside:

 

Planning your firewall holes is always an interesting exercise.  You might want to try this - get a piece of 1/8 inch thick plexiglass and cut it out just like the firewall.  Drill the engine mount holes in the plastic.  If you have your engine, attach it to the engine mount and hang the engine and mount from the ceiling or a hoist.  Now, you can move the plastic to the firewall or to the engine mount and use it as a template for locating firewall forward parts so they won't interfere with engine protrusions or the mount.  After much marking with a felt tip pen and when I was happy with all parts placement, I used the plastic to drill the stainless and the firewall.
