I quess it would come down to which ever carb you were more comfortable with. I have always had Holleys on everything except my old SuperBee. I service all my Holleys but am cofused just looking at the AV carbs. I will tell ya this tho, I had a guy around here fix the AV carb on the Bee and it was impressive afterwards. I just dont like messing with them. If you can work one either of them, stick with it...
