Need help perfecting the budget build hemi swap

The othe people on the road are a pain, I was rear ended I my belvedere once, and it does affect your driving style and confidence in others. I work in downtown Dayton and still drive my old cars, but it's a free for all when it comes to traffic lights. I try not to let others ruin my hobby, but it's hard when all of the work we put in them could be destroyed so quickly.
It's freaking heart breaking. I've mentioned it here several times. The guy who hit me looked stoned, had no license, it wasn't his car, and was involved in an accident in 2001 that killed someone. He hit me so hard, that when he T boned me, it pushed me through a field for 100 ft. My first reaction upon impact was to cut the wheel against his car, to push back. While reaching my other arm across my wifes chest to pin her in her seat. ( the car did have simpson 4 pionts.) The weird thing is before I came across the mountain, about a 1/4 mile from my turn off. I notice him coming down another mountain about 1/2 mile behind me. I was thinking this guy is really making ground on me.
He told the police that he didn't know I was making a left onto my rd, and since I was moving slow he was trying to pass me. A passer by that called the police, was a soldier with a broken foot, just back from Afganistan. We both watched this guy taking things from his car, and stashing them in the trunk. Both of us were under the immpression he was hidding drugs. We told the police, but he didn't seem interested. The cop impounded the car, and let the guy walk home. When the flatbed arrived for my Barracuda, the guy asked the driver for a lift into town. I went ape ****.
I had that car for years, and had installed the hemi as soon as they were available to the public, and had just weld new quarters on the week before.
