I worked at marina at Kinkaid Lake in Ill. the owner had a 68 GMC loaded with everything but it had a 305. ran grate but needed constant valve work. It was typical of them from day one. never could handle the long halls on the highway. Bullitins about every 4-6 months about the latest valve trick modification or replacement info.
