Nice to see all the pictures. Do you know what that 200-4R transmission came out of?
The ID tag is gone. I know it is an '87 and prior owner believed it came out of a Monte Carlo SS. I guess I'll find out when try a WOT shift. He had it behind a built 383 SBC in an '82 RX7. The non-performance 2004-R's shift at 3,000 WOT, he said this one was shifting at 5,000 rpm.
