Now I did have an old '79 Zeypher (like a Fairmont but made by Mercury) I had a 302,header, weiand intake, 650 Holly, and a mild cam under the hood, with a full on 85 gt suspension and the 10 hole wheels with it!! I ran duals with I can't remember the brand of turbo mufflers but when I had to get a sticker on it I was forced to put 2 converters on it. This was way back in the late 80's. I never had a gas smell on that one after I got the jets and the power valve dialed it and 'the old grandma's car scared the shit out of a lot of kids cruising on Fri and Sat nights... And ya Kno I had to leave it primer black... I wish I had some pics I could drop here but *sigh*
