Need help 1965 Barracuda 273 2bbl carb

Are you looking to keep it original?

If you just want to get it running and have fun driving it, post an ad for a 2 bbl carb and like @Dana67Dart said, a good muffler/exhaust shop can get you fixed up there. Those factory NOS resonators are high dollar.

With my 66, I kept it looking fairly stock exterior (but I love ralleye wheels) and interior (except for a couple gauges), but when you open the hood, the Air Gap stands out, even though I kept the v-belt setup on the magnum.

And I drive it all the time!
