Duh, well I had a brain fart, of course it wouldn't start if I unbolt the torque converter. Don't know what I was thinking. It is a 360, and I have already replaced the harmonic balancer. The converter is externally balanced, just not sure what else could be wrong. Are there different externally balanced converters for a 904? How can I verify I have the right one?
Again I am sorry about asking about unbolting the torque converter, I must be losing it.....my mind that is.
