Yeah, all good points. The flex-plate is 28oz external balanced like the engine and the harmonic balancer. The flex-plate is the standard 157 tooth and the converter is the upgraded 26 spline to match the trans hardened input shaft which is also 26 spline. The trans, converter and flex-plate are TCI but I have heard some negative things about them as a Company. It also costs me an arm and a leg to send these parts back to them for research. I have talked to a lot of people and they have told me to go with Hughes since they are local. That way if I have a problem with the setup they will tow it in and fix it (R & R). Also, I have heard good things about them as well. I have had 2 new transmissions and 3 new converters with this motor so either it is TCI or the motor. See what I mean. I can't believe that 2 transmissions are that bad, and they didn't send me the same one re-built but a totally different one. I guess I could dump the TCI set-up and go with an all new Hughes set-up from Lopers or Darryl Smith Racing, as I know Neil and Darryl. Besides, I could get it at their cost which would help. If I did that it would still cost me a couple of grand (Trans- $1,500, Converter- $700, Flexplate- $200) and then what if it doesn't fix the problem. That is pretty much the whole story, it just stresses me to no end and depresses me when I talk about it. I have talked to Darryl Smith Racing, B & B Machine, MHP, TCI Tech, etc. on and on and on.
