1965 Valiant 200 convertible (minor project)

Looks to me like an early model silenced air cleaner with a (probably) 1980 carb. Air cleaner housing was cut away to let it breathe better.

Late carb is OK, albeit with extra vacuum ports you don't need and has been lightly modified to work with the early throttle rod. A pre-67 carb would fit and look a little cleaner. An early unsilenced air cleaner would look better and breathe better than the smaller diameter silenced version. An early valve cover would also fit the late motor and would make it look more correct. If the late motor runs good, no reason to replace it unless you just want to be totally correct.
