**73 Scamp Mini Pro-Street Engine Swap**

That seems super heavy, about 500 pounds heavier than any A-body I've ever owned. My big block Dart was all steel with a 500" big block and full interior, it weighed 3000 without me in it.
It was a ladder bar though with plastic racing seats, but other than that it was fairly stock.

So your car weighed 2800lbs or so? That's the lightest dart in the world with a big block & not on a diet. That's all I got to say about that.
