I have a 71 Newport royal with the original 360 with the original 2 barrel Holley carb. The carb is interesting, albeit bad, as after 52 years the plastic idle setter and throttle control peice has worn so bad that my cars idle is all over the place, and the car can’t really be driven. I need a new 2 barrel that’ll bolt onto a stock 71 360 2 barrel intake. What’ll fit? And what’s good? By good I mean by any qualification, power, efficiency, ease of use, anything like that.
