I am replacing my Roto 5 with a TH200. The torque converter will be bolted up to the original "flywheel" that the Roto 5 used. 61-63 Buick Flexplates don't seem to be available or I would use one due to the decreased weight.

Wondering if anyone has done this and lightened the "flywheel" since it will now have a Torque Converter bolted to it. If so how much were you able to take our of it and has it been a good result.

Any info along this line is appreciated.

 

You need to call D&D aluminum V8. He will have what you need. http://www.aluminumv8.com/

 

Or, you can send me a PM and I'll sell you a good used Buick 215 flex plate for about half of what D&D charges. They are very helpful, nice guys but their prices are usually outrageous. I would not try to modify a Roto5 flywheel, the one on the left,it is not steel but cast. You could never get it thin enough to use without it becoming way to weak.
