The engine build became a John Twist Seminar. Quality Coaches asked me to help coordinate their March Seminar, and the first day we did Electrical, Hydraulics and Tool Box Tips. The second day was devoted to an engine 'short block'. I looked for an engine to do, and not finding one, volunteered Diane's. I might build an occasional B Series engine. John does many in a year and has been doing it since 1971. We had a great time and I learned a lot! Steve Bryan took some of these pictures, Jim Penoyer got his hands dirty, and Randy Byboth smoothed the procedures, fetched tools and provided parts if I forgot one at our garage. Thank you guys, and especially thank you John!
