Swapping a 360 from A-Body/auto into a '78 Dodge Van with factory 318/4 speed - Advice?

Well, it's time to stuff it back in...
I Made a template needed to drill out my existing small flywheel based on the drawing I found from more research here ( thanks for your old post @crackedback ).
Turns out the old 318 exhaust manifolds have the larger ports needed for the 360 so I lucked out there.
-fingers crossed! Doing it all alone so moving nice & slow. There's no room to spare, it's a very tight fit.
