Before the pushrod was replaced, we ran a compression test. Cylinder 6? (by the battery) was only at 33. The others were at 160. After replacing the pushrods and plugs, securing some bolts, replacing the gaskets, setting the timing, adjusting the valves, and securing the rockers, all 6 cylinders test at 160. All cylinders are firing, and all the engine runs a LOT more quietly. It doesn't sound like a sewing machine.
I took it around the "Lindbergh/Pershall exit curve" about 50MPH, which was about 2MPH too fast, maybe. I didn't hit the curb or anything, but slid about 4 feet sideways with all 4 tires. I watched the curb get closer and closer, and could've used a bit more power, but it straightened out and pulled through. The guy behind me hopped the curb and went into the grass.
