Engine mounting
Over the weekend I am going to put the weight of my engine on to my chassis for the first time. I don't want to create any local stress
areas.How big should I make the mounting plates?Thanks Glan

What ever size you make the plates they still put a big bending load on the lower members what is required is an extra tube at each side to take
the loads to a vertex.
With a spaceframe the loads should always be at vertexes where 3+ tubes meet as the tubes themselves have no strength/stiffness in bending .
It isn't always possible but the loads should be fed in as close as possible to the corners of bays.

Might be like this (BT?)
Make an apex at the side bay and put an extra tube as this one.

And then weld the plate to support the mountings.
