Here is the deal. The car ('85 GT Convertible) was running terrible with the stock "made by Holley" 4 barrel. So, I scrapped it in favor of the new "Street Avenger" series from Holley. Now, the car totally failed the emissions test in CO and NH (or something like that). Was wondering if just tuning the carb better would help or if I just need to put the stock carb back on to run through the test? Any of you have experience with something like this? I don't really want the pain of having to change carbs every 2 years!

Do all those stupid vacuum hoses on stock carb make that much difference in the emissions!?

Obviously I am CARB illiterate, so any help you can offer is appreciated!

Thanks,
AutoX
