Yeah, I thought of that too, but I'd do it 3 dimensionally, left back to right forward, etc. I think it would help, but I didn't run it past my friend. I think a stock frame could be stiffened up by drilling mounting holes diagonally and welding in some tubes. There is still a lot of stuff in there to have to work around on a stock setup, like shift linkage, 2 water lines, parking brake cable, etc.
My frame central tunnel is designed with torsional rigidity in mind, which is where my discussion with him started. He said it looked "hell for stout," which, considering he designed several of the bridges on the Houston 610 loop, I'll take that as "good enough."
