Yeah, I put one on my '66 about a month after I got it on the road. I started out with a 750 vac sec Holley and it was killing me on gas even after rejetting and adjusting. A buddy of mine has a AVS on his Duster and was telling me how happy he was with it, economy and performance. I was reluctant to buy one because I figured I would be giving up the performance of the Holley. WRONG!71Novacaine said:Anybody run this carb yet?? What are your thoughts?? Good or bad.
