Holley vs. Eddy 273

i have always ran a eddy 600 on my 273, than once I built my 318 the eddy went on it. no matter what i did it would always run rich but was still a good carb because of how simple they are. but I just put a holley 670 street avenger on today, and it runs way better, it just needs a little more tuning to get it right but the throttle response is way more responsive and crisp, plus there is a noticeable improvement in performance. good luck -Kory
