Just look at a waterboxer rear engine cross bar for inspiration.
It's rectangular tubing.
Also, of course, it's not loaded in the 'flat' plane, it' loaded in the
'vertical' plan if you follow me, which is stronger.
I even just USE waterboxer vanagon rear engine mounting cross bars for other
engine installations - I put one under an SVX engine - worked tres perfecto.
They're a bit heavy but super solid, and already the right length - ..one of
my fabrication rules .....( wood construction too ) ...when you find 'a
fitter' , you have to use it.
Plus rectangular is so much easier to work with, having flat sides, for
drilling holes in, bolting or welding things too, etc.
Another tip- build it 'in place' .
Get the engine where you want it.
Put the bar under it, make cardboard templates for the brackets you
need....cut those out on the work bench, set those in place on the
van/engine/bar , tack well them. Take the bar out, weld on it more, out it
back in to check the fit, etc.

Neil,
I'm not an engineer, but I would think that a tube with rectangular
crossection would have the greater strength, depending on the directions
loads are applied. Just my opinion.
