Do these #'s sound right?

Many of you know i just picked up a new, a car full wight 70 duster, and have been working the bugs out for the past few weeks. Well took the car to the local chassis dyno (dynojet) and it laid down 295 rwhp/ 296 rwtq. They claimed they had a demon in with virtually the same set up as me and it was with 4 hp of my car. Just wondering what others with similar setups have made or what you'd think based on your experiences. So far you guys have been really helpful. Thanks again. i realize that the carb isnt optimal but looking for thoughts on it the way it is. Any guesses on a 1/4 e.t and mph given decent 60ft's(in my mind 1.8-1.9) are welcome
