A 347 running 10.00 is most likely more setup for n/a performance. You need to be certain that the motor is setup for a big shot of nitrous, meaning rings gapped properly, very exhaust biased cam, big heads, tight converter, etc...
You don't just slap a 250 shot on a motor and expect it to run good. Anything over a 150 shot, the motor really needs to be setup to handle it.
All that said, my 427 is setup for more n/a performance and has been 10.37 on motor at 131. I'd expect to run 9.60-9.80 on a 100 shot and be out of gear on the top end.
All that said, take that Dart 347, with big heads/intake and nitrous cam, with about a 4500-5000 rpm stall and 7500 rpm shift point, and it could run in the 8s on the 250 shot.
