Stretched out the legs of the ole 81 today. Did a run to Baton Rouge for breakfast with the truck group. I think I am getting pretty close now on the carb adjustments. Driving there in the early morn I got about 12.8 MPG at 70-75, which was up from 9-ish before the rejetting and all. Also, found a bad PCV valve which I think was causing the oil usage (pushing it out some gaskets and dip tube. Coming back running AC at 70-75 I got 10. May not sound great but, my experience with straight 6s is they were not always super fuel efficient any ways. With the cam and mods to it, this may be its happy spot. I am still learning, but she is running good and sounds great.

And just some of the rides that showed up this morning.
