Engines In, But Still No Intake Manifold

I just found out that the new intake manifold won't be here for another week and 1/2, so hopefully it will be here by Friday 6/12.
That means the jeep will have been out of commission for over two months.
I went ahead and put the new engine in and over the next two weeks I'll bolt everything that I have back on.
I might also tow it over to the exhaust shop and have them hookup the old exhaust to the new header.
