Every time I set out to do one little thing I found another five things that could be better, so I did those too. And I started out with a nice airplane...not a project plane by any means.
Good luck with the rebuild!

Engine: Pponk - Now called Northpoint XP470 as Steve Knopp sold the STC , I'm having it built by Ly-Con in Visalia, Ca and I went with the option of doing 8.5:1 compression pistons and well as porting the cylinders.
Prop: MT 3 Blade prop - MTV-9-D I was able to find a good deal on this from someone doing the test work on the new Hartzell 3 blade
Engine Mount: Seaplanes West Engine Mount - Ok technically I didn't need this - my stock cessna mount is in great shape (for sale by the way) but after flying in a buddies plane I was shocked at how smooth it ran - when I asked he said upgrading to the Seaplanes west engine mount really smoothed it all out.
Seaplanes West Exhaust:- I probably could have gotten by with my old exhaust as well - was able to get this and the mount on the cyber monday deal. Saw the other post on seaplane west exhaust - got me thinking about this a bit - but after looking into it a bit more, its not an issue.
Ok now if I could just get someone to send me some $$ to pay for all of this I'll be good to go.

In my case it made no sense to hang all that new stuff on a 60 year-old, beat up, ugly, drilled and patched firewall, so I sourced a new stainless steel firewall and have been glad I did ever since. Not sure if that's an option for you or not. Best of luck with the total project.

Looks like I may be going down this route, I have a few smoked rivets around the cowling/firewall and one that the head popped off from some corrosion - so the right way to fix it is drill it out and address any corrosion - then prep the cowling for disimular metal touching (Aluminum & SS) and then it just seems silly not to replace the old patched up firewall at that point.
Where did you get your SS firewall?

Don't forget the titanium gear legs and axels!
