More problems.  I figured that at least I could always have fallen back on the early GM small cap distributor that I have been running in the '34 if nothing else worked out.  Well that is not going to happen.  One thing that I thought that would be cool was if I was able to modify my old Vertex (Joe Hunt) magneto to work with the EFI.  I'd remove the original coil and magnets, disable the mechanical advance, construct a shutter wheel to detect #1 cylinder, and maybe mount the ignition coil down on the bell housing (only place where there is room).  I was playing around with the magneto to see if I could do what I wanted when I decided to just drop it into place on the Crowler manifold while on the bench.  When I saw the clearances between the magneto and the rear throttle shaft bearing I knew that there was no way that a small cap distributor would ever fit.  There is barely enough room for the tall slender magneto.  The small GM distributor is just too big around ! This got me started looking through my old distributors to see what some of my options where.  So far all options have some advantages and some disadvantages.  At this time I am not sure what direction I will go.

    You can begin to see how close the body of the magneto is to the rear of the manifold !

    There is less than 1/8" !  Not much room to grow...

    Found an old Mallory dual point distributor.  This distributor has small diameter cap.  It clears just about the same as the Vertex magneto does.

    It fit in there but is really dwarfed by the height of the injector stacks !

    Well here is one that most people won't even know what it is.  For the younger folks it is a "Grant Spawlding Flamethower".  This was a dual coil distributor that was popular about 30 years ago.  I guess I am dating myself here because I used to run this distributor on my 12 second '55 Chevy many moons ago.  Anyhow it also fits.  It is slightly larger than the magneto but still looks like it would fit.  The condenser will go of coarse.  Some slight grinding of the rear throttle shaft boss might be necessary but I think I could make it fit.
