The Stromberg is one of the top 3 or 4 2-barrel carburetors ever made !
The only problem is that Stromberg used an aluminum throttle body. Like so many other carburetors with aluminum throttle bodies (think Q-Jet), 50k miles and the throttle body needs bushings. Once the throttle body has been bushed, 250k miles are not unreasonable.
I would highly suggest rebuilding the Stromberg (unless you own stock in Shell Oil

)
