Hi guys, new member here. I've got a NOS Man-A-Fre 4 x 2bbl set-up that's never been on a car. 2 of the carbs are NOS and the other 2 are like new. Just wondering if these are worth a darn on the street. Just guessing they are hard to tune and better for a American Grafitti Milner clone coupe(I think that's what he ran). Also, anyone know a rough value for this if I were to decide to sell.
