Barny here is another way of doing the Schertz Beam that
will take the load of the 20B. It consist of a 1/2 thick by
2-1/2 inch wide aluminum bar stock. A lot of metal places
will cut it to size for you.

The main download
is taken by two 1/2 inch square 4130 tube diagonal
braces up to the intake manifold bolt on one
side and any convenient bolt on the other side.
the 4130 tubes can be connected to the Schertz beam
with a couple of one by one bolted angle extrusions on each side.
Not shown on the rendering. Also not shown is the starter.
I have not modeled a starter yet :-)
The PSRU shown is Don Dunbar's.
