I'm by no means an engine builder but usually the cam manufacture specify what gear to run..you mentioned brass and iron...iron would be cast???maybe you need a steal gear (cnc)if there is such a beast...i'll try to look for you..good luck

Check the vertical movement on the distributor shaft. I know you have replaced two distributors, but check it anyway. I had a similar issue on my '66 4x4 with a 352 in it as the distributor shaft drove the oil pump and it suffered from vertical displacement. Went through three distributors until I changed to a dual point unit back then. Seems that the dist. would be forced upwards and cause excessive backlash on the drive gear. Just a thought.
