I had my '69 343 rebuilt a few years ago, but haven't been able to get back on to the project car. It is a 4bbl (10:1} and was rebuilt to stock specs with no performance enhancements. If someone out there has a need for it I would consider selling it. It is still on the engine stand and has been stored indoors continuously. I am in south central BC (Canada), about 2 1/2 hours via freeway from the Sumas WA border crossing. I have a Carter AFB for it also. All of the work was done by a professional engine rebuilder.
