Jeep 4.0 in 69 Barracuda

Ok Group, the beginning of this summer after I had purchased all the parts I had vowed to see this car start before the end of Summer. Its labor day weekend and I have 5 days off. Between today and Tues. There is no excuse, there is not that much work to be done. I just need to remain motivated.

I do have a question where I am seeking opinions.

Situation:
I am unsure on the state of the engine. I have used it as a mock up motor. I believe it does run, just not sure how well. The trans tunnel has not be cut for the top mount shifter, which is ok as i dont have a shifter installed in the transmission. And I am not sure the condition of the tranny yet as well.

Question:
Would be better to only install the Flywheel (which is need for crank position sensor), followed by the transmission. Or should i install the full clutch setup including the internal slave cyl.

Under the assumption it starts, if this engine is bad its getting replaced asap. If its a runner (aka not knocking) and sounds strong enough to move the car down the road, then its being removed so a new Oil Pan can be built correctly and new gaskets including head gasket installed. In both cases, I want to end up with a engine strong enough to run the car around town while working on other body work and such. Meanwhile a new motor build can hopefully get started in the winter a year from now, probably a 4.7 stroker (4.0L with the prior gen 258ci (4.2) crank and rods).

I don't have a drive line for the car, nor does it have a brake system yet. So I am kind of leaning on installing what is needed for the electronics to start the engine.

Is there any thing I am missing as to why I should consider a full install of everything?
All my parts are oem replacements for the 4.0L and matching transmission including the hydro internal clutch slave cyl, at this time there is no concern of compatibility.

Thanks,
John
