200-4R Behind a 340 and Reid Bellhousing Build

My flexplate came with the adapter as well. I originally went with a 10" non lock up 2700 stall converter as recommended by Art Carr. After having the transmission rebuilt a year or so ago, I called PTC and had them build a 3500 stall. The whole transmission works better now and I ran 3/10ths of a second faster.
