So, I just ordered another 40ft of 1.75x0.120 DOM for tomorrow noon pickup. I want to get most of the hard to reach bars in before door bars and such. Then I am going to also X brace the frame rails under the drivers compartment and over the rear axle - that will be tied into the rear shock mount.
Also, for HP, it seems the best bang for the buck down the road is a used R5P7. There are a few for sale for $10-25K. That definitely is down the road, but 800+HP and lots of RPM seems like a solid combo.
