Need help perfecting the budget build hemi swap

I bought a 73 Duster when I was working in the oilfield back in the late 70's for $150. I had a mangled passenger quarter and was missing the marker light. The hole was a perfect place for wasps to get in the trunk. The car cost me another $75 because of the cortizone shot I had to get. I was stung on the knuckle and my arm swelled up to my elbow in minutes....
Can I say Muther ****** on this forum ? No, okay, the little futher mucker, cost me 9 hrs of Prednisone dripping from an IV, but I slept through that, and the steroid ate a hole in my stomach, so now I have to take the purple pill. That said, it took 3 weeks to recover, but I'm much better.
I first noticed my frame tweek when I couldn't get the exhaust around the shocks evenly. The guy who sold me the car had redone the hole interior, but under it were floor boards that weren't welded to the front unit body.
