emmissions
any suggestions on helping to pass emmissions? I have the engine listed in my sig. other than the deletion of the edelbrock 750 and added a road demon 625. I am in desperate need of passing. I also bought a new 3" high flow cat to put on which i didnt have before. so that will be going on after i tune the carb. any suggestions would be appreciated

turn down the fuel pressure ...... retard the timeing .....make sure you have fresh oil in the crank case . Make sure the car is HOT when you take 'r in ( so the cat is working ) . Put some crap in the tank that makes your fuel burn cleaner ....I am not sure if a higher octane will benifet you ......as there has been debates ( really heated ones ) on wither or not it is a performance inhancer at our level of engine setup .
good luck to ya man
