To put an inline six like a 250/292 to my 87 700R4 Trans in my Chevy 4x4 pick up? It has a TBI engine instead of a carb. That means a one piece rear main seal. Soooo, do I install a different torque converter from an older 700 that fit the 80s vintage inlines? Do I have to change the flexplate on the six to make it work? I know it will bolt up but need to know this before I begin. I guess I need to know if the earlier torque converter will work for me or not without changing the trans as mine is excellent. :confused: Henry
