Ya Stan, bite the bullet and let them put it together! 

I'm going one step further with mine, it will be completely assembled and taken through the cam break in before I even want to see it. Sure it costs a little extra, but if you let the engine builder assemble, start and break in the cam, then it has a warranty he can't walk away from by saying you did something wrong. I don't know about you, but I assume you are about where I am, old enough to want it done so it can be driven and enjoyed.

I just don't have the energy for pulling engines anymore!

I have a friend down here who has rebuilt a gazillion engines including farm tractors. 
He even knows how  rebabbit whatever it is you rebabbit.  Whatever rebabbitting is.
He's taking over assembly duties while I supervise.

 If my memory serves me correctly, in the model T era you could make your own bearings by pouring molten babbitt material in the rod and main caps. The caps were then scrapped to get hem close to size and then the crank was put in and spun to get them to the correct size. It may be a little more complicated than that, but that is the general idea I think. 67Newport2009-07-30 15:25:10

I just found this.
 
What’s a babbitt?      The babbitt that we use in Model T and  A bearings (along with a host of other antique engines; both gas and steam) is a type of “white metal” bearing material known in industry as “tin-based” babbitt. (as differing from the sometimes softer lead-based babbitt; of which more later) According to records,  the Ford factory used a babbitt of approximately eighty five percent tin, seven percent copper, and seven percent antimony; the balance assumed to be impurities and various alloying agents. At the time, that type of babbitt was simply referred to a “hard pein babbitt”; the term referencing the tensile strength and high ductility* (compared to lead babbitt) of the material and the usual method of post-pour swaging or peining that was employed, not only to seat the babbitt in the journal box, but to compress the babbitt into a harder surface.
Ford accomplished this peining process when; after boring and semi-fitting/finishing the bearing by scraping (of which little was done) the crankshaft was clamped tightly in the new bearings and  the bearings were “burned in.”   More precisely they were “burnISHED in.” This burning in process involved the crankshaft being so tight in the bearings that when revolved by a thirty-horsepower machine the bearings were liberally oiled; the oil was supposed to smoke, or the bearing was considered to be too loose and shims were pulled and the whole process started over until the oil smoked!  
    There have been endless discussions and much derision of this process.  K.R. Wilson was highly critical of it, though not, as we shall see, because it didn’t work but rather because it was at variance with what he sold.  As a mass production method, for this type of bearing, is was an ingenious system!
