Its beautiful, but with that investment, I feel like it would be hard to ever in the future change my mind.
I have a decent investment in small block stuff. I am hopeful with the latest Ritter block, so don't ever anticipate a change. This old dinosaur will do everything I need it to, and not running a Gen 3 Hemi actually makes it unique. Now if an iron race tall deck Gen 3 block ever became available...
You might also consider adding a 3/4 axis CNC to your shop.
That may be coming once I enclose and air condition the other side of the shop...some day.
Did you mention the alloy?
6061-T6 for everything except the tensioner assembly and idler pulley standoffs. Those are steel.
