hi, i have a 331 with a vic jr, 700 cfm carb. i was woundering if that does not pass emissions, can i lean out the air/fuel ratio and make it pass? its going in an 86 mustang.
any help would be very good.

I'm not sure how the emissions test is in MA, but there is no way it would pass here without the factory fuel injection, even if the carb was tuned really well, it couldn't touch the low emissions of EFI.

yea i was thinking if i tune it were its way to lean it would have a chance

Its not gonna pass if they have 'visual inspection' in Mass.
Obviously having the EFI replaced with a carb will make it fail even before the test begins.

331fox is my brother. if the car was originally carbed from factory (a 6-cylinder) it might squeeze past the emissions guy?
the place i go for testing is hit and miss on the underhood check, so we might be ok.

thanks,
carl
