Anyone have desktop dyno be willing to get me a ballpark?

Yep... once I get the bugs worked out (rear end, radiator, timing, break in the engine, etc) .. and then get some seat time, learning how the car drives, I may take it for a spin down the ¼ mile. I know I was pleasantly surprised when I got my V6 Mustang (305hp 3.7L V6) to do 13.81 @ 102mph .. I'm hoping the Dart will do about the same.
