Just rebuilt a flathead that has run very well in the past. 07-03 cam .006 lash 30* timing .049 jet. I am testing it on a water brake dyno (analog) that I have never used before. No smoke, no blowby. Low end seems stout, 9.3 ft lbs torque @ 4200. The dyno says it is dead @ 6500 with only about 3 ft lbs of torque. My best guess is I messed up the timing or it has slipped. Can anybody think of anything beside timing? After posting I am going to put on a known quality animal for testing for comparison as I do not have another flathead. I set the timing with a degree wheel and then find a key I can tap in, in this case I used a #6
