I arrive at Tommy's for three days of dyno work. Frank and I have it on the pump and make our first pull before lunch, things are going well. Recheck valve lash and start tuning using Renagaid 110 for fuel. We get the engine tuned to where if timing is changed up or down it lowers power, if jetting is changed it lowers power. The best way I found to read plugs after two pulls is to chuck them in a lathe and remove the threads and ground strap. It leaves just the porcelain and what ever color the base is and its very easy to read. End of day one.

Tomorrow cam change and other stuff.
